The Cat Magnetic Speed Sensor, model 318-1178, is a passive sensor that does not require an external electrical power supply. It generates an alternating current output signal with a waveform that is generally sinusoidal. The voltage and frequency of this signal are proportional to the surface speed of the actuator as it passes the sensor’s pole piece. The sensor is designed for high position accuracy and is particularly suitable for applications with speeds above 50 rpm.
