Dongfeng KL truck parts Steering angle sensor assembly C3636510-90000

At the core of the assembly is a contactless hall-effect sensor that delivers ultra-precise steering angle data. With a resolution of 0.1°, it accurately measures steering wheel rotation (from -720° to +720°, covering 4 full turns) and transmits real-time digital signals to the ECU—enabling the ESP system to adjust brake force and engine torque within 50ms of detecting oversteer or understeer. The sensor’s linearity error is ≤0.5%, ensuring consistent feedback even at extreme steering angles (critical for heavy-haul or narrow-road maneuvering). Unlike potentiometer-based sensors that wear out and lose accuracy over time, this contactless design endures 2 million+ steering cycles (equivalent to 8 years of heavy use) without signal degradation, maintaining reliable control of the truck’s stability systems

Built to withstand the harsh conditions of the steering column—constant vibration, temperature fluctuations, and electromagnetic interference (EMI)—the assembly uses robust materials and shielding. The outer housing is made of impact-resistant PC/ABS plastic (UL94 V-0 flame-retardant rating) that tolerates temperatures from -40°C (cold starts) to 85°C (engine bay heat) without warping. The internal circuit board is coated with a 0.2mm conformal epoxy layer, protecting components from dust, moisture, and oil ingress (meeting IP6K7 waterproof standards). A copper EMI shield surrounds the sensor module, blocking interference from the truck’s electrical system (e.g., alternator, ignition coils) and ensuring signal stability. Unlike unshielded sensors that produce erratic data, this design guarantees accurate angle detection in all operating environments

Engineered with safety as a priority, the assembly includes multiple safeguards to prevent steering control failures. It features dual-channel signal output (primary and backup), allowing the ECU to cross-verify data—if a discrepancy exceeds 1°, the system triggers a fault code and activates a limp-home mode (maintaining basic steering control) to avoid sudden stability loss. A built-in over-voltage protection circuit (clamping at 28V) shields the sensor from electrical spikes, while a thermal shutdown function (activating at 90°C) prevents overheating. The sensor also monitors its own internal health (e.g., circuit continuity, hall-element functionality) and sends diagnostic data to the ECU, enabling technicians to quickly identify issues via a scanner. These features meet ISO 26262 functional safety standards, eliminating risks of incorrect steering angle data leading to ESP malfunctions

Designed for hassle-free replacement by fleet technicians or DIY owners, the assembly simplifies setup with plug-and-play functionality. It includes all necessary hardware: 3 M5×12mm stainless steel mounting bolts, lock washers, and a foam gasket that reduces vibration transfer to the sensor. Installation takes 15–20 minutes: remove the old sensor, align the new assembly with the steering column’s reference marks, tighten the bolts to 12 N·m torque, and plug in the 6-pin connector. Unlike aftermarket sensors that require manual calibration via specialized tools, this OEM unit is pre-calibrated at the factory—the ECU automatically recognizes the sensor and syncs it with the steering system within 30 seconds of ignition. For maintenance, the sensor requires no periodic servicing, and its durable construction ensures long-term reliability. Each unit undergoes angle accuracy testing, vibration trials (10–2,000 Hz), and EMI resistance checks, backed by a 24-month warranty against defects (e.g., signal failure, housing cracking, connector damage)
