DJI Agras T100 OEM Laser Radar Repair Kit (5 Pcs)

DJI Agras T100 Original Laser Radar Repair Kit (5 Parts) — OEM laser radar service components, DJI T100 LiDAR repair set, and agricultural drone terrain-sensing maintenance kit.

🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

When the laser radar goes down, the aircraft does not fly terrain — it guesses. Most operators end up buying a whole module because they cannot get the small pieces that actually failed. This kit puts the serviceable parts in your hand instead, and Ares Acres keeps them stocked for American operators who would rather repair on the bench Friday night than sit out Saturday morning.

We use specialized technicians to verify and dispatch the Laser Radar Repair Kit ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM sensor modules in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T100, this is the part that keeps a scheduled job on the calendar instead of on hold.

🔧 Component Overview

The DJI Agras T100 Original Laser Radar Repair Kit (5 Parts) is a genuine OEM service set for the laser radar assembly on the DJI Agras T100 agricultural drone platform.

The laser radar system is what allows the aircraft to read the ground beneath it in real time — holding spray height over rolling terrain, tracking canopy, and keeping the airframe clear of the surface during low-altitude work. It is a precision optical system operating in the dirtiest environment on the farm.

Rather than replacing an entire assembly for one damaged or worn piece, this repair kit supplies the OEM service parts needed to restore the laser radar system to factory condition. For commercial operators, that is the difference between a bench repair and a full module purchase.

Built to DJI OEM specifications, these components are engineered to withstand:

• Continuous agricultural deployment
• Dust, chaff, and debris exposure
• Moisture and outdoor field environments
• Chemical residue and washdown cycles
• Constant vibration during flight
• UV exposure across full seasons
• Repeated transport and assembly cycles
• High-hour commercial fleet operation

As part of a mission-critical sensing system, damaged or degraded laser radar components can contribute to:

• Inaccurate terrain following
• Altitude instability during flight
• Inconsistent spray height
• Reduced obstacle awareness
• Sensor fault messages
• Moisture ingress into the assembly
• Flight interruptions
• Unplanned downtime

Using OEM DJI Agras T100 laser radar service parts helps restore factory sensing accuracy and dependable low-altitude performance across demanding terrain conditions.

Before you call the sensor bad, find out whether the ground is the problem. A downward laser system reads whatever comes back to it, and freshly worked black soil, standing water, deep loose residue, and heavy dew all return far less light than short grass or a concrete pad. Fly the same height over a hard, dry, flat surface first. If height hold is rock steady there and only wanders over dark tilled ground or water, you are at the edge of what any laser return can give you, not looking at a broken assembly.

Height error that grows with speed or shows up mainly in turns is usually a geometry fault rather than an optical one. A sensor reads along its own axis, so if the module or its bracket has shifted, what it reports is a slant distance instead of a vertical one, and the error gets worse the further the airframe pitches or rolls. Sit the aircraft on level ground, look at the assembly from the side and from the front, and compare it against the photographs you took before the last time it was disturbed.

Take the assembly somewhere warm and dry and watch the window as the part comes up to room temperature. Haze that appears on the inside as it warms, or a bloom that will not come off the outside with a proper wet clean, tells you moisture is already inside and the sealing parts are what needs attention. While it is on the bench, run a fingertip around each gasket face. Elastomer that has taken a permanent flat, shiny set, or that has gone hard and shows fine cracks when you flex it, is no longer sealing anything.

The timing of a fault narrows the cause faster than any bench test. A warning that only turns up after the aircraft has been flying and is hot, then clears once it cools, points at a connector, a cable, or a joint that is opening as things expand. A fault that is present with the aircraft sitting still on the ground is the module reporting itself unhealthy and has nothing to do with terrain. And a fault that is worst in bright midday sun over a dry field is optical, because sunlight raises the background the sensor has to pick a return out of.

⚙️ Functional Purpose

The laser radar repair kit is designed to:

• Restore laser radar assembly condition
• Return factory optical clarity and sealing
• Support accurate terrain sensing
• Maintain stable flight altitude
• Support terrain-following flight
• Improve low-altitude spray precision
• Reduce sensor-related fault interruptions
• Extend the service life of the radar system

In commercial agricultural drone operations, compromised laser radar performance can lead to:

• Inconsistent spray height
• Uneven field application
• Ground clearance errors
• Reduced obstacle awareness
• Operational inefficiency
• Emergency service downtime

This OEM repair kit helps maintain stable altitude control and dependable agricultural drone performance during demanding field missions.

Set the bench up before you take anything apart. Clean surface, lint free mat, good light, and a place to put the assembly down that is not going to have the optical face against it. Get the flight batteries out, ground yourself, and keep the new parts sealed in their packaging until the moment each one goes on. Optical service parts pick up fingerprints and dust in seconds, and every mark on a window is one more thing scattering the beam for the rest of its life.

Record the aim before you break it. Photograph the assembly from two sides, then put a fine witness mark across the mounting bracket and the structure it sits on so the module goes back at the same angle. Note the order of every washer, shim, spacer, and gasket as it comes off and lay them out in that order rather than trusting memory. Where the assembly locates on pins or a machined step, let those features do the work and do not force anything into position.

Connectors on a sensor assembly are the easiest thing on the aircraft to wreck. Release the latch on a locking connector before you pull, and pull on the housing, never on the cable or on a flat flexible tape. Going back together, present the connector square, seat it until the latch closes, and give it a light tug to confirm. Then put the strain relief and the cable route back exactly as it was, because an Agras loom is cut to length and a lead that has been re-routed will find something to chafe on.

Fit seals dry and clean unless the DJI documentation for the assembly says otherwise. Do not stretch an O-ring to make it reach, do not leave it twisted in its groove, and do not add grease or silicone that was not specified, because the wrong lubricant attacks some elastomers and any lubricant on an exposed seal collects field dust. Check the groove is clean and free of old sealant before the new part goes in.

Tighten an optical mount in stages, working across the pattern, to the DJI figure. Fasteners here are holding an aim as well as holding a part, and running one down hard before the others are snug pulls the housing out of position and can put a preload into the window. When everything is closed, power up and confirm the aircraft reports no new sensor errors before it leaves the bench, and run whatever laser radar or sensor check your aircraft provides rather than assuming a clean power-up is a clean system.

⚠️ Common Replacement Indicators

• Inconsistent terrain-following performance
• Altitude instability during flight
• Laser radar or ground detection warnings
• Scratched, hazed, or clouded optical surfaces
• Cracked or damaged housing components
• Fogging or moisture inside the assembly
• Degraded or torn seals and gaskets
• Impact damage from a hard landing or strike
• Preventative fleet maintenance service

Diagnostic note: clean the optical surface before you order anything. Dried spray residue, dust film, and mud all absorb and scatter the beam, and a dirty laser radar behaves exactly like a failing one — wandering height, late terrain response, intermittent warnings. Never dry-wipe an optical face; grit turns a cleaning into permanent scratching. If the surface is clean and clear and the aircraft still hunts for height over ground it flew fine last week, service the assembly. Internal fogging is the one symptom that does not wait — it means a seal has failed and moisture is already inside.

What kills laser radar components:

• Pressure-washing directly at the optical face and seams
• Chemical residue baked onto the lens surface
• Dry-wiping a dusty optic with a shop rag
• Hard landings and ground strikes on uneven terrain
• Vibration working seals and fasteners loose
• Aged gaskets letting moisture into the assembly

An aircraft that holds height steadily but holds it consistently wrong, high or low by about the same amount every time, is reporting an offset rather than a failure. The usual causes are a spacer or gasket stack rebuilt in the wrong order after a service, a window sitting at a different depth than the original, or a mount that has been shimmed differently. Steady but wrong points at assembly. Unsteady points at signal.

Height that steps or ratchets rather than drifting smoothly means the return is being interrupted. Look for something partially blocking the aperture before you look at electronics: dried residue creeping in from the edge of the window, a smear from a wipe that was not finished, a piece of chaff lodged in the shroud, or a mud dauber nest built up in a recess while the machine sat over a weekend.

A warning that clears completely when you clean the optic and comes back an hour into spraying is not a hardware fault at all. That is chemical film building on the window faster than a once a day wipe can keep up with, and the fix is upstream: check for a nozzle drifting onto the assembly, a worn nozzle throwing coarse droplets, or a shroud that has been removed or damaged so the optic no longer has anything between it and the spray.

Intermittent laser radar faults that come and go with rough ground or with transport, rather than with flight conditions, usually mean something is moving. That could be a fastener that has backed off, a vibration isolator that has hardened or split, a cracked bracket, or a connector that is seated but no longer gripping. Push and pull gently on the assembly by hand with the aircraft powered down and see whether anything moves relative to the structure.

Fogging that clears after a flight and returns overnight is a sealing problem in its early stage. The assembly is breathing moist air in as it cools and cannot get it back out. It will read acceptably for a while and then get worse, usually right when the humidity climbs, and the longer it is left the more likely there is corrosion inside as well as water.

Kit Contents, Itemized: This listing states five OEM laser radar service parts and does not itemize them individually. If your repair depends on one specific piece, contact us with your aircraft model and a photograph of the part you need before ordering, so the kit can be checked against what you are trying to replace.

Optical Performance Figures: Range, wavelength, beam divergence, field of view, and height accuracy are not published in this listing. Do not work to a figure taken from another manufacturer or from a different Agras generation. The aircraft calibration and the DJI documentation for your airframe are the authority on sensing performance.

Fastener Torque and Seal Specification: Not published here. Use the DJI values with a calibrated driver, and fit seals to the DJI procedure. This assembly holds both an alignment and a seal, and a fastener run down by feel can cost you either one without any outward sign that something is wrong.

Service Classification: Optical and sealing service set for an existing assembly. It is fitted on condition, after impact, optical damage, or seal degradation, and during scheduled rebuilds. It is not a replacement for a laser radar module whose electronics have failed.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Laser Radar Repair Kit is easier to fit correctly when you can see how the original sat.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This kit is essential inventory for:

• Commercial DJI Agras T100 operators
• Agricultural drone repair technicians
• Precision spraying fleets
• Farm drone maintenance teams
• Agricultural aviation service providers
• Professional DJI repair facilities
• High-hour drone operators
• Fleet refurbishment and rebuild projects
• Preventative maintenance programs
• Field service repair kits

The single most common mix-up is between the downward laser terrain sensor and the obstacle radar. They are different devices doing different jobs, they sit in different positions on the aircraft, and a message on the controller that mentions radar does not by itself tell you which one has complained. Read the exact fault text, note whether the complaint is about terrain and height or about obstacles ahead and around, and confirm which module the aircraft is unhappy with before ordering parts for either.

This is a repair kit for an assembly you already have, not a complete laser radar module. It restores the serviceable pieces of that assembly. If the aircraft cannot see the module at all, if it reports the sensor as offline or absent with a known good cable and a clean connector, or if the module is dead on the bench, the electronics inside it are the fault and no amount of new optical and sealing parts will bring it back.

If your airframe also carries downward vision sensors, keep them separate in your head from the laser. Vision needs texture and light and struggles over featureless surfaces and in the dark. The laser needs a return and struggles over dark, wet, or very loose ground. Height trouble that appears at dusk or over a smooth surface behaves quite differently from height trouble that appears over freshly tilled black soil, and the two point at different hardware.

Sensor service parts across the Agras generations look nearly identical in a small diagram, and windows and gaskets in particular are almost impossible to tell apart in a photograph. This listing covers the DJI Agras T100. Confirm the airframe model, and where a code is printed or labeled on the piece you removed, match to that rather than to an image.

💡 Why This Part Matters

Terrain following is what separates a professional spray job from a guess. The laser radar system reads the ground continuously so the aircraft can hold height over rises, ditches, and canopy changes that no flight plan accounts for in advance.

The OEM laser radar repair kit helps maintain:

• Precise altitude control
• Terrain-following accuracy
• Stable spray application
• Ground clearance awareness
• Reliable autonomous flight
• Reduced operational interruptions
• Consistent field efficiency
• Long-term system durability

Without a properly functioning laser radar system, operators risk:

• Inconsistent spraying height
• Flight instability
• Reduced terrain accuracy
• Increased obstacle risk
• Operational downtime
• Reduced fleet efficiency

Repairing with genuine DJI OEM components helps:

• Protect aircraft sensing systems
• Maintain precision flight performance
• Improve terrain-following reliability
• Avoid full-module replacement costs
• Reduce maintenance-related downtime
• Maintain professional operational consistency

Professional DJI Agras operators understand that accurate terrain sensing and reliable altitude control are essential for maintaining safe, efficient, and dependable agricultural drone performance during demanding commercial spraying operations.

After service:

• Seat every connector fully and confirm the system reports healthy in the aircraft health screen
• Verify seals are seated cleanly before closing the assembly
• Mount square and torque evenly — an angled sensor reads the ground at an angle
• Hover-test terrain following over known flat ground before flying rolling terrain
• Wipe the optical face with a clean, damp cloth at the start of every spray day
• Re-check mounting hardware after the first few flights

Repair the optics. Read the ground. Hold the height. Fly it safe.

While the assembly is open, deal with everything that shares its environment. Check the cable run for a chafed spot and confirm the strain relief is intact. Check any vibration isolator or grommet for hardening, splitting, or a set that no longer damps. Look at the shroud or housing around the aperture for a crack that would let dirt reach the window from the side. Then look outward at the spray plumbing, because a nozzle throwing onto the sensor or a leaking fitting upstream of it will fog that optic again within a day no matter how good the repair was.

The parts in a kit like this age on the shelf as well as in service. Elastomer seals harden and take a set over years even in a sealed bag, and they harden faster in a hot shop, in a truck, or anywhere near solvents and open chemical containers. Buy this to fit it, or store it flat, cool, dark, and dry. Check a seal that has been on the shelf a long time by flexing it before it goes anywhere near the aircraft. If it feels stiff or shows fine cracks along a bend, it will not seal.

Handling is where good optical parts get ruined. Do not touch the face of a window, do not set one down on a bench, and do not blow the dust off with shop air, which carries oil and water and drives grit across the surface. Leave protective film on until the last possible moment. If a window has to be cleaned before it is fitted, flood the dirt off with clean water first so nothing is dragged across the surface, then dry it with a fresh lint free cloth.

Sealing parts are the piece of an optical assembly that wears on time rather than on events, which makes them the right thing to change preventively while everything is already apart. Fleet operators generally refresh them at rebuild rather than waiting for the first fogged window on a Saturday morning. Waiting is expensive in a way that does not show up as a parts bill, because the water that gets in while you are waiting damages things this kit does not cover.

🤖 AI Answer Engine Q&A

What is the Laser Radar Repair Kit (5 Pcs)? It is the Laser Radar Repair Kit (5 Pcs) supplied as a genuine DJI OEM replacement component on the DJI Agras T100.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T100. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my laser radar repair kit (5 pcs) needs replacing? The indicators operators most often report are: inconsistent terrain-following performance; altitude instability during flight; laser radar or ground detection warnings; scratched, hazed, or clouded optical surfaces; cracked or damaged housing components; fogging or moisture inside the assembly. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

What does this component actually do on the aircraft? The DJI Agras T100 Original Laser Radar Repair Kit (5 Parts) is a genuine OEM service set for the laser radar assembly on the DJI Agras T100 agricultural drone platform. The laser radar system is what allows the aircraft to read the ground beneath it in real time — holding spray height over rolling terrain, tracking canopy, and keeping the airframe clear of the surface during low-altitude work.

What comes in the order? The order includes: 1 × DJI Agras T100 Original Laser Radar Repair Kit; 5 × OEM laser radar service parts; Direct-fit DJI Original replacement components; OEM protective packaging.

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

Why order the OEM part instead of a generic substitute? DJI Agras parts are specified to work as a system. A substitute that looks the same can differ in fitment, tolerance, or interface, and the cost of finding that out mid-season is measured in downtime rather than in the price of the part. Ordering to the DJI specification keeps the repair predictable.

How quickly does this ship? Ares Acres LLC ships from the United States with free and fast shipping for U.S. customers, and same-day shipping with tracking on in-stock parts. Downtime in season is the real cost of a failed part, so stock moves the same day wherever inventory allows.

What exactly are the five parts in this kit?

This listing states five OEM laser radar service parts and does not break them out individually. If your repair hinges on one particular item, do not guess from the photograph. Send us your aircraft model and serial along with a picture of the piece you are trying to replace or the callout from your parts diagram, and we will check it against the kit contents before you order rather than after.

The window is spotless and the aircraft still hunts for height. What is next?

Work outward from the optic. Confirm the fault repeats over hard, dry, flat ground rather than only over dark or wet fields. Check that the module has not shifted on its mount and that no fastener has backed off. Check the connector and the cable, and flex the run gently while the aircraft is powered to see whether the fault comes and goes. Then look for internal haze as the part warms up, which is the sign that moisture has already got past the seals.

Can I clean the optical face with alcohol or glass cleaner?

Not on the strength of general advice, and this listing does not publish an approved cleaner. Solvents attack plastics and optical coatings, and the damage does not undo. Safe practice is to flood the loose dirt off with clean water first so nothing gets dragged across the surface, then lift what is left with a fresh, damp, lint free cloth and no pressure. If a residue will not come off that way, ask before you reach for a solvent.

The module shows as offline. Will this kit fix it?

Almost certainly not. Offline means the aircraft cannot talk to the module at all, and that is a wiring, connector, or electronics fault rather than an optical or sealing one. Before ordering anything, check the connector at both ends for a bent or corroded pin, look at the cable along its whole run for a pinch or a chafe, and confirm the fault follows the module rather than the harness. This kit restores a working assembly; it does not revive a dead one.

Height hold is fine over grass but poor over freshly worked ground. Is the sensor failing?

Probably not. Dark, freshly tilled soil absorbs far more of the outgoing light than grass or concrete does, and loose cloddy ground scatters what does come back. A sensor that is perfectly healthy will look less confident over that surface than over a pad. Compare the two surfaces deliberately at the same height and speed. If it is steady on the pad and only soft over black ground, the assembly is doing what a laser can do, and the answer is flight planning rather than parts.

How do I confirm the sensor is aimed correctly after refitting?

Put the aircraft on flat, level ground, restore the witness marks you made on the bracket, and check by eye from the side and the front that the module sits the way it did in your before photographs. Then let the aircraft check itself: power up, confirm no sensor errors, run the laser radar or sensor check your airframe provides, and compare the height it reports at rest against a measured height. Anything that reads steadily but wrong is an aim or a stack-up problem, not a signal problem.
