Cat® Passive Low-Output Over-Mold Speed Sensor

- Big Rig World carries Genuine OEM and Aftermarket parts to repair your vehicle at the lowest prices.

Cat passive speed sensors do not require any external electrical power supply. The output signal is an alternating current and the waveform function of the actuator is generally sinusoidal in nature. Voltage and frequency are both proportional to the surface speed of the actuator as it passes the sensor’s pole piece. Injection molded nylon is applied directly over the magnet and coil.
