522-1643: Engine Speed Sensor

Description:
Cat single Hall effect sensors have Hall elements. Active Hall effect sensors require an external electrical power supply. Waveform is function of the target gear square wave output. Frequency is proportional to surface speed of the target gear as it passes the sensor, but the voltage level is not (unlike passive speed sensors). Hall effect sensors can detect down to zero speed (unlike passive speed sensors).

Attributes:
• One Hall element
• One output, 3 wires (power, return, signal)
• Available in both fixed nose length and adjustable depth housings

Applications:
• Used where zero speed or near-zero speed detection is required.
• Transmission output speed
• Speed
• Timing
