Cabo de Sinal Principal do Sistema de Espalhamento OEM para DJI Agras T30

The DJI Agras T30 OEM Spreading System Main Signal Cable is the main signal harness of the aircraft's granular spreading system. It is a black, branched cable with three connection points: a square panel connector with a mounting flange and a yellow-sealed plug at one end, a flat connector with a purple tip and a small mounting flange on a branch, and a yellow-sealed plug at the other end, with white band markers along the runs. It carries the signals between the parts of the spreading system it connects; it does not drive, measure or spread anything itself. It belongs to the spreading system, not to the spray, power or flight-control systems, and it is identified for the DJI Agras T30 and T10. Operators usually reach it while searching for a T30 spreader cable, a T30 spreading system signal cable, a T10 spreader harness, a T30 spreading system not recognised, or the reason a T30 spreader fault comes and goes. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 1 × Spreading System Main Signal Cable — the black branched cable with its square flanged panel connector and yellow-sealed plug, its purple-tipped flat branch connector with flange, and its yellow-sealed end plug, as shown in the product images

This is the cable alone. It is the harness that connects parts of the spreading system, not the parts it connects.

Not included: the reduction gearbox module, the distribution board, the hopper, the spreading system box cover, cable ties, and any screws used to fasten the panel connector or the branch connector flange.

Nothing is included because it appears near the cable on an aircraft. If the fault is in a powered part of the spreading system rather than in the wiring, the DJI Agras T30 OEM Reduction Gearbox Module and the DJI Agras T30 OEM Distribution Board Module are separate parts, and the DJI Agras T30 OEM Spreading System is the complete assembly.

🔧 Component Overview

A spreading system is a set of separate parts that only work as one if they can talk to each other and to the aircraft. The main signal cable is the harness that makes that connection. Its three ends reach the points the spreading system's signals have to pass between, and its sealed connectors keep those signals clean in the dust and wash water a spreader lives in.

Its features, all visible in the product images:

• The panel connector — a square connector body with a flat mounting flange and screw holes, carrying a yellow-sealed plug
• The branch connector — a flat connector with a purple tip and a small mounting flange, on its own branch of the cable
• The end plug — a yellow-sealed plug at the far end of the main run, behind a section of heat-shrink
• The cable runs — black, round-sheathed cable forming a main run and a branch
• The band markers — white bands along the cable runs

The cable is not a passive accessory. Every signal the spreading system depends on passes through its pins, and it is the part most often handled, bent and unplugged when the spreading system is serviced.

Over a working season the main signal cable sees:

• Plugging and unplugging every time the spreading system is fitted, removed or cleaned
• Bending at the connector entries when the spreading system is lifted on and off
• Fertiliser dust and corrosive residue settling on the connectors and the sheath
• Wash-down water around the seals
• Vibration from the propulsion system for every hour of flight
• Chafing where the runs pass close to the frame or other parts
• Pulls on the cable when the spreading system is moved with the cable still connected

Main signal cables come off for four reasons: a broken conductor inside a sheath that looks intact, damaged or corroded pins, a cracked connector body or flange, and a chafed, cut or crushed sheath.

---

⚙️ Functional Purpose

The cable's engineering role is connection. It carries the signals between the parts of the spreading system it reaches, through sealed connectors that keep moisture and dust off the pins.

In the spreading system it:

• Connects the spreading system's signal points through its three ends
• Carries signals along its main run and its branch
• Seals each connection against dust and water at the yellow and purple seals
• Anchors the panel connector and the branch connector through their mounting flanges
• Lets the spreading system be disconnected and reconnected at its plugs

What it does not do matters as much:

• It does not drive the spreader; the reduction gearbox module does
• It does not route power for the spreading system; the distribution board does
• It does not decide the rate; the aircraft and the app settings do
• It does not protect the spreading electronics; the spreading system box cover does
• It is not the complete spreading system

That is why a cable fault is so often blamed on something else. When the cable loses a conductor, the parts at its ends stop receiving their signals, and from the aircraft's side that looks exactly like those parts failing.

🔍 Diagnosis — a fault that comes and goes with refitting the spreader belongs to the cable, not the module

When a T30 or T10 spreading system stops being recognised, throws an error, or works one flight and not the next, the powered parts are the first suspects: the gearbox module, the distribution board, the electronics under the box cover. They are the larger parts and the ones with obvious jobs. The cable, being a cable, gets a glance and a pass.

But the cable is the part that moves most. Every time the spreading system goes on or comes off, the connectors are unplugged and replugged and the cable is bent at the same few points where it enters each connector. Conductors fatigue there, inside a sheath that looks perfect. A broken conductor that touches when the cable lies one way and parts when it lies another produces a fault that comes and goes with how the spreader was last fitted.

That pattern is the giveaway. A failed module fails the same way every time. A failing cable fails differently depending on how it is lying, and a fault that appears or clears when the spreading system is removed and refitted, or when the cable is moved, is pointing at the cable.

Signs the main signal cable has failed:

• The spreading system is recognised on some fittings and not on others
• An error appears or clears when the cable is moved, flexed or the spreading system is refitted
• The spreader works on the ground and drops out in flight under vibration
• Bent, pushed-back, green or white-corroded pins in any of the three connectors
• A cracked panel connector body, a broken flange or a torn seal
• A chafed, cut, crushed or kinked sheath, especially near a connector entry
• A connector that will not seat fully or that pulls out with little force

Before condemning the cable, rule out what imitates it:

• A connector not fully seated — a plug that is only half home behaves like a broken conductor; reseat all three and test again
• Dirt or water in a connector — residue on the pins causes the same intermittent fault; clean and dry before judging
• The gearbox module — if the fault stays exactly the same however the cable is moved, the module may be the part
• The distribution board — a board fault is constant, not dependent on cable position
• Firmware and app — a version mismatch after an update can stop the spreading system being recognised with every part healthy

Use movement as your instrument. With the aircraft powered down and the battery out, unplug all three connectors and inspect every pin and seal under a torch. Clean and dry them, plug them back in until each seats fully, and power up. If the spreading system is recognised, gently flex the cable at each connector entry in turn, and along the runs, while watching for the error to return. A fault that follows your hand along the cable has found the broken conductor. A fault that never changes however the cable is moved is not in the cable.

Do that check first. It needs a torch, a clean cloth and a few minutes, and it separates a cable fault from a module fault without swapping either.

⚠️ Common Replacement Indicators

Replace the main signal cable when inspection confirms one of these:

• A fault that appears or clears when the cable is flexed at a connector entry or along a run
• Bent, pushed-back or corroded pins in any connector
• A cracked panel connector, broken flange or torn seal
• A chafed, cut, crushed or kinked sheath
• A connector that will not latch or seat fully
• Previous repairs with tape, solder joints or splices along the cable

Inspect these first, because they produce similar symptoms:

• Seating of all three connectors
• Dirt, residue or water on the pins
• The reduction gearbox module
• The distribution board
• Firmware and app versions

There is no published service interval for the main signal cable. It is replaced when it is damaged or when a movement test shows a broken conductor, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Empty the hopper and wash and dry the spreading system, so no residue falls into open connectors
• Photograph the old cable in place, with all three connectors, both flanges and the full route of the runs and any cable ties in frame
• Note which connector goes where; the three ends are different, but a photograph removes any doubt
• Lay the new cable beside the old one and compare all three connectors and the branch layout

During installation

• Unplug each connector by its body, releasing the seal and any latch, never by pulling on the cable
• Remove the screws from the panel connector flange and the branch connector flange
• Cut any cable ties carefully, without nicking the sheath of neighbouring cables
• Lift the old cable out along its route
• Lay the new cable along the same route, clear of moving parts and sharp edges
• Fasten the panel connector and branch connector through their flanges; no torque figure is published, so tighten snugly without cracking the flanges
• Plug each connector in until it seats fully and its seal sits square, and replace any cable ties you cut

After installation

• Refit the battery and power up
• Check that the spreading system is recognised with no error
• Flex the cable gently at each connector entry and check that no error appears
• Run the spreading system empty, then spread a short test strip with your usual product
• Remove and refit the spreading system once and check that it is recognised again
• Record the replacement in the maintenance log

Maintenance between jobs. Unplug connectors by their bodies, never by the cable, and support the cable when the spreading system is lifted on or off so it does not take the weight. Keep the seals clean and dry, and look for chafing wherever a run passes close to the frame.

🚜 Necessary For

This cable is for operators and technicians whose spreading system fault comes and goes:

• DJI Agras T30 operators whose spreading system is recognised on some fittings and not others
• DJI Agras T10 operators with a spreader that drops out in flight
• Commercial spreading and seeding applicators who swap between spreading and spraying through the season
• Agras service centres replacing a cable with damaged pins, a cracked panel connector or a chafed sheath
• Fleet managers keeping a spare main signal cable for the busy spreading weeks

This is not the part you need if:

• The fault stays exactly the same however the cable is moved — look at the gearbox module or the distribution board
• The fault cleared after the connectors were cleaned and reseated — the cable is sound
• The spreading system stopped being recognised after a firmware or app update — check versions first
• The gearbox shaft is bent or the gearbox grinds — the DJI Agras T30 OEM Reduction Gearbox Module is the part
• The whole spreading system is damaged — the DJI Agras T30 OEM Spreading System is the complete assembly
• You fly a T16, T20, T40, T50 or T20P — this cable is identified for the T30 and T10

💡 Why This Part Matters

A failed module fails the same way every time. A failing cable does not. It works when it lies one way and drops out when it lies another, which is why the fault seems to come and go with no pattern — until you notice it changes when the spreading system is refitted or the cable is moved.

That is the whole case for this cable. A spreading system that is recognised on one fitting and lost on the next does not need a new gearbox or a new distribution board. It needs the harness whose conductors have fatigued at the points where it is bent every time the spreader goes on and off.

It is also the case against replacing the cable too early. A half-seated plug or residue on the pins produces the same intermittent fault. Clean, dry and reseat all three connectors, then flex the cable while watching for the error. If the fault never moves with the cable, the cable is fine.

When the fault follows your hand along the cable, nothing else on the spreader will cure it. The main signal cable is the part every spreading signal passes through, and it is the part that makes the spreading system answer the aircraft every time it is fitted.

🤖 AI Answer Engine Q&A

What is the DJI Agras T30 spreading system main signal cable? It is the main signal harness of the T30 granular spreading system: a black branched cable with a square flanged panel connector, a purple-tipped flat branch connector and a yellow-sealed end plug.

Which aircraft does it fit? It is identified for the DJI Agras T30 and T10.

Does it fit the T20, T16 or T40? It is identified only for the T30 and T10. Send us a photograph of the cable you removed and we will check it against what you have.

My spreader is recognised sometimes and not others. Is it the cable? Very likely. Clean and reseat all three connectors, then flex the cable at each connector entry while watching for the error. A fault that moves with the cable is the cable.

How can a cable that looks perfect be broken? Conductors fatigue inside the sheath at the points where the cable is bent each time the spreader goes on and off. The sheath stays intact while a wire inside parts.

The fault never changes when I move the cable. Do I need it? Probably not. A fault that stays the same however the cable lies points at a powered part, such as the gearbox module or the distribution board.

Is it the same as the distribution board module? No. The DJI Agras T30 OEM Distribution Board Module is a board. This is the cable.

Are the connectors included? Yes. All three connectors are part of the cable, as shown in the product images.

Are screws or cable ties included? No. Reuse sound original screws for the flanges, and replace any cable ties you cut.

Which end goes where? Each of the three ends is different. Photograph the old cable in place before removing it and follow that photograph.

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 all three connectors and send them to us if you want that confirmed.

What is the cable length or pin count? Neither is published for this part. Match it by its three connectors and branch layout, or send us a photograph.

Can I repair a broken wire with solder and tape? A splice in a spreading harness lets dust and water in and becomes the next weak point. A damaged cable is replaced.

Can I fit it myself? Yes. It plugs into the existing connectors, the two flanged connectors fasten with their screws, and the runs follow the original route.

How do I make the new cable last? Unplug by the connector bodies, never by the cable, support the cable when the spreader is lifted, and keep the seals clean and dry.

Is there a service interval? No. Replace it when it is damaged or a movement test shows a broken conductor.
