An inductive proximity sensor, a key component of the wheel steering control system (2WS/4WS). Its function is to precisely detect a metal tab on the steering knuckle, which informs the control module that the wheels have reached the "straight ahead" position. This is essential for correctly switching between steering modes and for the automatic centering of the rear axle.

| Brand (Machine Type) | Model |
|---|---|
| JCB (Backhoe Loaders) | 3CX, 4CX (models with three steering modes) |
| JCB (Telehandlers) | Loadall (wide range of models, e.g., 520, 525, 526, 528, 530, 533, 535, 540) |
The list above is for reference. We recommend visually comparing the sensor with your old part before purchasing.
Problems with sensors often stem from moisture and corrosion on the contacts. Before connecting the new part, thoroughly inspect and clean the plug in the machine's wiring harness. Use a dedicated HYPTRON electrical contact cleaner spray to ensure a perfect connection and avoid reading errors.
The proximity sensor informs the control module when the steering axle wheels are in the straight position. This is critical information that allows the system to safely switch between steering modes (e.g., from road mode to 4-wheel steer). A failure of this sensor paralyzes the entire system and limits the machine's maneuverability.
Replace the sensor if your machine has steering problems. Common symptoms include:
