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 sensors pole piece. Injection molded nylon is applied directly over the magnet and coil.

Attributes:
● High output
● Bolt-n-go style mounting bracket
● Lowest cost

Applications:
● High position accuracy, NOT recommended for use in applications <50 rpm
● Lower output voltage
● Typical applications include engine cam and transmission output
