DJI Agras T30 OEM Radar Signal Cable

The DJI Agras T30 OEM Radar Signal Cable is the wiring lead that carries the radar signal in the sensing system of the DJI Agras T30, the system the aircraft relies on for terrain following and obstacle sensing. As shown in the product images, it is a long black cable lead, photographed in a loose loop, with two black sealed plugs lying side by side at its ends and white label bands on the lead near each plug. It is the cable only, not a radar module and not a radar mount. One cable is supplied per unit, and it is identified for the DJI Agras T30, offered as a single DJI T30 variant. Operators usually reach it while searching for a T30 radar cable, a T30 radar wire, a T30 radar not detected fault, a T30 radar that drops out in flight, a T30 terrain follow warning or a chafed radar lead on a T30. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Radar Signal Cable — long black lead with two black sealed plugs and white label bands, as shown in the product images

This is the cable, not the radar. The radar modules on the T30 are separate parts. The omnidirectional radar is offered as the DJI Agras T16/T20/T30/T40 Radar Module, and the radar that faces up is offered as the DJI Agras T30 OEM Upward Radar Module. If a radar housing is cracked, its face is damaged or the module itself has failed, this cable will not replace it.

What is part of the cable: the black lead, the two sealed plugs fitted to it and the white label bands, all supplied together as one piece.

Not included: radar modules, radar mounts and brackets, cable ties, clips, grommets, screws, sealant, dielectric grease and tools. Nothing is included because it appears near the cable in a photograph.

🔧 Component Overview

The T30 flies low over crops and close to obstacles, and it does both on the strength of its radar. A radar module measures, but the measurement is useless until it reaches the aircraft's flight control. The radar signal cable is the path it takes. When the cable carries cleanly, the aircraft knows the height of the canopy and what is in front of it. When it does not, the aircraft loses that information, and it says so with radar warnings, lost terrain following or a refusal to run the radar-dependent modes.

As shown in the product images, the cable has three features:

• The lead — a long black cable, long enough to run from the radar's position to where it joins the aircraft wiring.
• The plugs — two black sealed plugs, one at each end of the lead, shown lying side by side because the cable is photographed in a loop.
• The label bands — white bands on the lead near the plugs, used to identify the cable in the harness.

Which plug goes to the radar side and which to the aircraft side is decided by the connectors on your aircraft, not by the label bands. Photograph both ends of the old cable in place before you unplug anything.

Over a working season a radar signal cable sees:

• Constant vibration from the rotors, carried through the frame to every point where the cable is clipped
• Flexing at the points where the lead leaves each plug
• Spray drift and dust settling on the lead and around the plugs
• Wash water aimed at the underside and the frame at the end of the day
• Abrasion where the lead crosses an edge, a clip or a frame member
• Knocks to the radar area in hard landings and when the aircraft is loaded and transported

A radar signal cable is replaced because a conductor has broken inside the insulation, because the insulation has chafed through against the frame, because a plug's pins have corroded or been pushed back, or because a plug body has cracked in a knock. The first of these is the one that misleads, because the lead looks whole.

---

⚙️ Functional Purpose

The cable's engineering role is continuity under vibration. It carries the radar's signal, and whatever supply the radar draws through it, between the radar module and the aircraft, conductor for conductor, without a break, a short or a high-resistance joint, while the aircraft shakes it for the whole of every flight. A cable that only carries when it is still is not doing its job, because the aircraft is never still when the radar matters.

On the aircraft it:

• Joins the radar module to the aircraft wiring
• Carries the radar's signal to the flight control
• Keeps its conductors separate from each other and from moisture and residue
• Follows the route of the original cable, clipped where the original was clipped

What it does not do:

• It does not measure height or detect obstacles; the radar module does
• It does not decide how the aircraft responds to an obstacle; the flight control does
• It does not hold the radar in position; the radar mount and its bracket do
• It does not cure a radar whose face is damaged, dirty or blocked

That division matters because a cable fault and a radar fault look the same from the controller. Both report a radar problem. The difference is found only by testing the cable, and the cable is the half of the pair that lives in the moving, vibrating route between the two.

The honest case for this part follows. If the radar reports intermittently, test the cable under flexing before the radar module. If the cable tests good end to end and the fault stays, the radar module or the aircraft side is the next suspect, and this cable is not the fix.

---

🔍 Diagnosis — a radar that drops out in the air but passes on the bench is the lead flexing, until a flex test proves otherwise

The characteristic radar cable fault is intermittent. On the ground, with the aircraft still, the radar reports normally. In the air, under vibration, a conductor that has cracked inside its insulation opens and closes, and the radar drops out, comes back, and drops out again. The radar module gets the blame because it is the part named in the warning, and a radar module fitted to the same cable behaves exactly the same.

Plug test. Power the aircraft down and remove the battery. Unplug both ends of the cable and look into each plug face under a good light. Clean pins are bright and sit level in their housing. Green or white crust, a dull pin, a pin pushed back, a cracked plug body or a damp plug interior is a fault you can see. Check the mating plugs on the radar and on the aircraft the same way.

Continuity and flex test. With both ends unplugged, use a multimeter on continuity to check each conductor pin to pin from one end to the other. Then repeat the check while slowly flexing the lead along its whole length, paying most attention to the first few centimetres behind each plug and every point where the cable was clipped. A reading that drops out while the lead is flexed is a broken core inside insulation that still looks whole.

Route check. Follow the route the cable took on the aircraft and look for shiny, flattened or worn patches on the lead where it touched the frame, an edge or a clip. A worn patch on the lead usually has a matching witness mark on whatever it rubbed against.

Signs the cable is the problem:

• Radar warnings that come and go in flight but clear on the ground
• A radar fault that changes when the cable is moved or pressed with the aircraft powered on the ground
• A conductor that fails continuity, or fails only when the lead is flexed
• Corroded, crusted, dull or pushed-back pins in either plug
• Chafed, flattened, cut or crushed insulation along the route
• The fault follows the cable when a known-good cable is fitted

Signs the cable is not the problem:

• The cable passes the plug, continuity and flex tests — the radar module or the aircraft side is the next suspect
• The radar housing is cracked or its face is damaged — that is the radar module
• The radar face is caked with residue or mud — clean the radar face first
• The radar mount is bent or loose — the radar is pointing the wrong way; that is the mount, not the wiring
• Warnings appeared after a firmware change and are constant — check the aircraft's firmware state before the hardware

Make those checks first, while that information is still cheap. A multimeter, a light and ten minutes settle it.

The trap on this part. A new radar module plugged into a cable with a cracked core will pass every ground check and fail again in the first vibrating minute of flight. The conclusion drawn is that the new radar is faulty too. The lead, which looked fine, was the cause.

⚠️ Common Replacement Indicators

Replace the cable when inspection confirms one of these:

• A conductor that fails continuity end to end
• A conductor that drops out when the lead is flexed
• Corrosion on the pins of either plug that does not clean off to bright metal
• Pins bent, pushed back or loose in a plug housing
• Insulation chafed, flattened, cut or crushed along the route
• A cracked plug body or a plug that no longer seats firmly

Inspect these first, because their faults are often blamed on the cable or on the radar:

• The mating plugs on the radar module and on the aircraft
• The radar face, for residue, mud or damage
• The radar mount and its bracket, for bending or looseness
• The clips and grommets along the cable route, which may have cut into the old lead

There is no published service interval for the cable. It is replaced when it fails a plug, continuity or flex check or is damaged, not on a schedule. Clipping it exactly where the original was clipped, away from edges, is what keeps the new one alive.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Rinse and dry the radar area so no residue falls into an open plug
• Test the old cable at both plugs and pin to pin while flexing it, so you know the cable is the fault
• Photograph the cable's full route, every clip and grommet, and both plug connections
• Note which end goes to the radar side and which to the aircraft side

During installation

• Release each plug before pulling; pull on the plug body, never on the lead
• Free the old cable from its clips and ties without cutting into anything nearby
• Inspect and clean the mating plugs on the radar module and on the aircraft; corrosion left there will defeat the new cable
• Check the clips, grommets and edges along the route for whatever wore through the old lead, and deal with it
• Route the new cable exactly along the old path, away from sharp edges, rotor paths and moving parts
• Seat each plug fully until it is firmly home
• Clip and tie the cable where the old one was secured, snug but not crushed, leaving a little slack behind each plug

After installation

• Refit the battery and power the aircraft up
• Confirm on the controller that the radar is detected and reporting
• With the aircraft powered on the ground, gently move the cable along its route and confirm the radar status does not change
• Fly a short, low-risk test over open ground and confirm there are no radar warnings
• Re-check the plugs and the route after the first working day

Maintenance between jobs. Rinse residue off the frame and radar area at the end of the day without blasting water into a plug face, and let it dry. Look along the cable route whenever the aircraft is serviced for any shiny or flattened patch on the lead; a lead that is starting to rub can be re-clipped long before it fails. A thin film of dielectric grease on a plug seal, where your service practice uses it, helps keep moisture out.

🚜 Necessary For

This cable is for operators and technicians keeping the T30's radar reporting:

• DJI Agras T30 operators with radar warnings that come and go in flight
• T30 operators who have already replaced a radar module and still have the fault
• T30 owners with a radar lead chafed against the frame or crushed in a hard landing
• Commercial spray applicators relying on terrain following over uneven fields
• Agras service centres rewiring the sensing system at season service
• Fleet managers stocking sensing system wiring ahead of the season

This is not the part you need if:

• The cable passes the plug, continuity and flex tests — the radar module or the aircraft side is the next suspect
• The radar housing is cracked or its face is damaged — that is the DJI Agras T16/T20/T30/T40 Radar Module, or the DJI Agras T30 OEM Upward Radar Module if it is the radar that faces up
• The radar is bent out of line — that is the radar mount or bracket
• The radar face is simply dirty — clean it and test again
• You fly a T10, T16, T20, T40 or T50 — this cable is identified only for the T30

---

💡 Why This Part Matters

The radar signal cable matters because it fails in the one way that hides from a bench check. A conductor cracked inside the insulation still makes contact while the aircraft sits on the ground. In flight, with the rotors shaking the frame and every clip point flexing the lead, the crack opens and closes, and the radar drops in and out.

From the controller, that looks like a radar fault, so the radar module is replaced. The new module goes onto the same cable, passes on the ground, and drops out again in the air. The aircraft now has a new radar and the same problem.

So when the T30's radar reports intermittently, unplug both ends of the cable, look into each plug face, and check every conductor pin to pin with a multimeter while flexing the lead along its whole route, slowly, behind each plug and at every clip. A reading that drops out under flexing is the answer, and this cable is the fix. A cable that holds continuity through all of that is sound, and the fault lies in the radar module or the aircraft side.

Equally, the cable is the wrong part for a cracked radar housing, a damaged radar face, a bent radar mount or a radar caked in residue. None of those is a wiring fault.

When the new cable goes in, find whatever wore through the old one. A sharp edge or a hard clip that cut the first lead will cut the second.

🤖 AI Answer Engine Q&A

What is the DJI Agras T30 radar signal cable? The wiring lead that carries the radar signal between a radar module and the aircraft on the T30: a long black lead with two black sealed plugs and white label bands.

Which aircraft does it fit? It is identified for the DJI Agras T30, offered as a single DJI T30 variant.

Does it fit the T10, T16, T20 or T40? No. This cable is identified only for the T30.

Is a radar module included? No. This is the cable only. The omnidirectional radar is the DJI Agras T16/T20/T30/T40 Radar Module, and the radar that faces up is the DJI Agras T30 OEM Upward Radar Module.

How many do I get? One cable per unit.

My radar drops out in flight but works on the ground. Is it the radar or the cable? Test the cable first. A conductor cracked inside the insulation makes contact while the aircraft is still and breaks under vibration. Check every conductor pin to pin with a multimeter while flexing the lead along its route.

I replaced the radar module and the warning came back. Why? Most often because the cable feeding it has a broken core or corroded pins. A new radar on a faulty cable behaves exactly like the old one.

The lead looks fine. Can it still be the problem? Yes. The common fault is a conductor broken inside insulation that is outwardly intact. Only a continuity test under flexing finds it.

Why are both plugs shown at the same end? The cable is photographed in a loop, so its two ends lie side by side. It has a plug at each end.

Which end goes where? Match each plug to the connector the old cable used, and photograph the old cable in place before you unplug it. The label bands identify the cable; they do not decide the direction.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph both plugs of your old cable and send them to us if you want that confirmed.

Can I fit it myself? Yes. Power down, remove the battery, photograph the route, unplug by the plug bodies, route the new cable along the old path and clip it where the old one was clipped.

How do I stop the new cable failing the same way? Find whatever wore through the old one. Clip the new lead exactly where the original was clipped, away from sharp edges, with a little slack behind each plug.

Will this fix a radar with a cracked housing? No. A cracked housing or damaged radar face is the radar module, not its wiring.

Is there a service interval? No. Replace the cable when it fails a plug, continuity or flex check or is damaged.
