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.
