Dual-channel Hall-Effect Speed Sensor
The Sensors use a magnetically biased Hall-effect integrated circuit to accurately sense movement of ferrous metal targets. The sensor is a self adjusting digital output rotary position gear tooth sensor designed for use in automotive camshaft sensing as well as other speed sensing applications. The sensor has an open collector output which is short circuit protected.
As the signal is sampled, the logic recognizes an increasing or decreasing flux density. The output will turn on (BOP) after the flux has reached its peak and decreased by an amount equal to the hysteresis. Similarly the output will turn off (BOP) after the flux has reached its minimum value and increased by an amount equal to the hysteresis. The sensor is sealed in a probe type package for physical protection and cost effective installation.
If power is inadvertently wired backwards, the sensor will not be damaged
