Wheel Speed Sensor: Description and Operation
WHEEL SPEED SENSOR
The speed sensor is the contactless type that detects the rotating speeds of a wheel. It is composed of a permanent magnet and coil. When the gear
pulsers at each wheel turn, the magnetic coil in the speed sensor alternates, generating voltages with frequency in proportion to wheel rotating speed.
