coil. Each time an exciter tooth and its adjacent space move

past the tip of the sensor, an AC voltage "cycle" is generated.

The number of AC cycles per revolution of the vehicle's wheel

depends on the number of teeth in the exciter, which is

programmed into the antilock controller. Using the

programmed data, the controller can calculate "vehicle

speed" by analyzing the frequency of AC cycles sent by the

speed sensor. (The frequency of AC cycles is directly

proportional to wheel speed.)

AC voltage is also proportional to speed, but voltage is not

used to determine speed. It is only an indication of AC signal

strength. The amount of AC voltage generated by a specific

speed sensor depends on the distance, or "gap," between

the tip of the sensor and the surface of the exciter. Voltage

increases as the sensor gap decreases.

The WS-20

™

wheel speed sensor is installed in a mounting

block that is affixed to the axle housing. (See Figure 2.) A

spring loaded retainer bushing provides a friction fit between

the mounting block bore and the WS-20

™

sensor. The friction

fit allows the WS-20

™

sensor to "slide" back and forth under

force but to retain its position when force is removed. This

DESCRIPTION

The WS-20

™

wheel speed sensor is an electromagnetic

device used to obtain vehicle speed information for an antilock

controller. When the wheel rotates, the sensor and an exciter

(e.g. rotor or tone wheel) generate a simple AC signal. This

signal is sent to the controller, which analyzes the data and

commands the antilock system accordingly.

Specifically, the speed sensor consists of a coil, pole piece,

and magnet. The exciter is a steel ring or gear-like device

that has regularly spaced high and low spots called "teeth."

The sensor is mounted in a fixed position, while the exciter

is installed on a rotating member so that its "teeth" move, in

close proximity, past the tip of the sensor.

The WS-20

™

wheel speed sensor is available in both straight

and right angle versions, to accommodate axle/wheel space

limitations. (See Figure 1.)

OPERATION

The sensor's magnet and pole piece form a magnetic field.

As an exciter tooth passes by the sensor, the magnetic

field is altered, which generates AC voltage in the sensor
