Wheel Speed Sensor: Description and Operation
Wheel Sensor Operation
The sensor unit consists of a gear-shaped sensor rotor and a sensor element. The element contains a bar magnet around which a coil is wound. The
sensor is installed on the back side of the brake rotor. Sine-wave current is generated by the sensor as the wheel rotates. The frequency and voltage
increases as the rotating speed increases.
