OPERATION
• Wheel speed sensor is a kind of a pulse
alternator. It consists of encoders (a plate on
which north and south pole sides of the magnets
are arranged alternately) for detecting wheel
speed which rotates at the same speed of the
wheels and speed sensors. This sensor outputs
frequency pulse signals in proportion to wheel
speed.
