Rotational Speed Sensor
The Rotational Speed Sensor detects the rotational speed of components such as the crankshaft, camshaft, gearbox shaft, or wheel hubs—depending on vehicle configuration. It sends real-time signals to the ECU, aiding in fuel injection timing, ABS/ASR functions, torque management, and overall engine optimization.
Built with robust magnetic/electromagnetic sensing technology and a sealed, vibration-proof housing, this sensor ensures stable operation even in extreme temperature, dust, and vibration environments common in heavy commercial vehicles.
