{"product_id":"dji-agras-t40-oem-backward-vision-sensor-radar-module","title":"DJI Agras T40 OEM Backward Vision Sensor Radar Module","description":"\u003cp\u003eThe DJI Agras T40 OEM Backward Vision Sensor Radar Module is the rear-facing obstacle-sensing unit of the aircraft: the module that looks behind the airframe while the aircraft reverses, backs out of a headland or flies the return leg of a pass tail-first. It is the sensing part of the rear position in the obstacle-sensing system. It sits in the backward vision radar bracket at the rear of the airframe and reports to the aircraft through its own signal lead. The module is identified for the DJI Agras T40 and T20P. Of the three parts at that rear position — the bracket that aims it, the lead that carries its signal, and the module itself — it is the only one that does the sensing, and it is the one to replace when the fault is in the sensing.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

It backs out of headlands, reverses along rows, and on many routes flies the return leg tail-first rather than turning round. Forward sensing cannot see any of that. The backward vision sensor radar module is the part that watches the space behind the aircraft while it moves that way.\u003c\/p\u003e\n\u003cp\u003eThe module sits at the rear of the airframe, held in the backward vision radar bracket, and connects to the aircraft through its own signal lead. It is a separate unit from the omnidirectional radar, which is a different module in a different position with a different job. The two are often called \"the radar\" in conversation, and the confusion between them is the most common way the wrong part gets fitted.\u003c\/p\u003e\n\u003cp\u003eAt the rear position, three parts have to be right at once:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe bracket\u003c\/strong\u003e decides where the module is looking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe signal lead\u003c\/strong\u003e carries what the module reports back to the aircraft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe module\u003c\/strong\u003e does the looking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA fault at the rear can live in any of the three, and the symptom the operator sees is usually the same: rear obstacle sensing that cannot be trusted. Only one of those three faults is cured by a new module.\u003c\/p\u003e\n\u003cp\u003eThe module lives on the outside of an aircraft that works low, close to crop, wet with spray mix and covered in field dust.

Proving that reason takes a few minutes with a cloth, a look from behind and a reseated connector, and it comes before the module comes off the aircraft.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe module's engineering role is detection behind the aircraft.

What can be said is what its position and name support: it is the sensor responsible for the rear, and nothing else on the aircraft takes over that job if it stops working.\u003c\/p\u003e\n\u003cp\u003eWhat the module does not do matters as much as what it does:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt does not aim itself — the backward vision radar bracket sets the direction it looks, and a bent bracket aims a healthy module at the wrong space\u003c\/li\u003e\n\u003cli\u003eIt does not carry its own signal — the lead does, and a chafed or loose lead makes a healthy module look faulty\u003c\/li\u003e\n\u003cli\u003eIt does not replace or repair the omnidirectional radar, which is a separate module with its own position\u003c\/li\u003e\n\u003cli\u003eIt does not change obstacle-avoidance settings on the remote controller; it supplies the rear view those settings act on\u003c\/li\u003e\n\u003cli\u003eIt does not clean itself — a dirty sensing face blinds a module that has nothing wrong with it\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — the bracket aims it, the lead carries it, only the module sees\u003c\/h2\u003e\n\u003cp\u003eA rear-sensing problem has four possible owners: the sensing face, the bracket, the lead and the module. Three of them are cheap to check and one is the module itself. Work through them in that order, because the module is the only one that has to come off the aircraft and the only one whose replacement changes nothing if the fault was elsewhere.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOwner 1 — the sensing face.\u003c\/strong\u003e Spray residue, mud or a film of water on the module's face produces false rear warnings or missing ones from a module that is working perfectly. Clean it gently with a soft damp cloth, dry it and test again. A fault that disappears when the face is clean was never a module fault.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOwner 2 — the bracket.\u003c\/strong\u003e The module reports what is in front of its face. If the bracket under it has been bent by a tail-first landing or a rear strike, the module is still sensing accurately — at the wrong piece of space. Look at the module from behind and from the side: it should sit square to the airframe. A tilted or skewed module on a tight bracket is a bracket problem, and the part to fit is the DJI Agras T40 OEM Backward Vision Radar Bracket, not a new module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOwner 3 — the lead and connector.\u003c\/strong\u003e A loose, chafed, corroded or water-damaged connection produces dropouts, warnings that come and go, and faults that change when the aircraft is flexed or the lead is moved. Reseat the connector, inspect the run for chafe, and look for corrosion on the pins. A fault that changes when the lead is touched is a lead fault.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOwner 4 — the module.\u003c\/strong\u003e When the face is clean, the module sits square, the connection is sound and the aircraft still reports a fault for the rear sensing position — or rear sensing is plainly absent while the forward sensing works — the fault is in the module.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat a failed module tends to look like in the field:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA fault reported against the rear sensing position that survives cleaning, reseating and a power cycle\u003c\/li\u003e\n\u003cli\u003eNo rear obstacle response at all, while forward sensing behaves normally\u003c\/li\u003e\n\u003cli\u003eRear warnings that are wrong in a consistent way rather than intermittently, with a clean face and a square module\u003c\/li\u003e\n\u003cli\u003eVisible damage to the module body or its sensing face after a strike — a crack, a chip or a breach\u003c\/li\u003e\n\u003cli\u003eSigns that water has been inside the module after washing or a heavy-rain job\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat points away from the module:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFaults in every direction of travel, not only when reversing\u003c\/strong\u003e — look at the omnidirectional radar and the aircraft's wider sensing first\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA warning that comes and goes when the aircraft is moved or the lead is flexed\u003c\/strong\u003e — the lead or connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA module that is visibly tilted or skewed\u003c\/strong\u003e — the bracket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProblems that clear when the face is cleaned\u003c\/strong\u003e — nothing needs replacing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRun that list in order, first, while those checks still cost nothing.

When the rear sensing cannot be trusted, the aircraft is working blind in exactly the direction it is moving.\u003c\/p\u003e\n\u003cp\u003eThe case for this module is narrow, and it is meant to be. The rear position is three parts — a bracket that aims, a lead that carries, and a module that sees — and all three produce the same complaint from the cab: rear sensing that is wrong. The module is the only one of the three that does the seeing, and it is the right part only when the fault is in the seeing.\u003c\/p\u003e\n\u003cp\u003eThat makes the honest advice simple. Do not fit this module to cure a tilted mount; a new module in a bent bracket looks at the same wrong space. Do not fit it to cure a warning that comes and goes when the lead is flexed; a new module on a damaged lead reports the same dropout. Do not fit it to cure a fault that is present in every direction; that belongs to the omnidirectional radar. And do not fit it before the face has been cleaned, because a dirty face is the most common rear fault of all and the only one that costs nothing.\u003c\/p\u003e\n\u003cp\u003eWhen those are ruled out — clean face, square module, sound lead, and a fault that still sits at the rear sensing position — the module is the part. At that point nothing else on the aircraft can stand in for it, and no setting on the controller replaces a rear sensor that has stopped sensing.\u003c\/p\u003e\n\u003cp\u003eSend us a photograph of the label on the part you removed and we will match it before it ships, so the module that arrives is the one the rear position needs.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.
