GMR proximity switch sensor, as one kind of Hall sensor, is waterproof and anti-interference, which can be widely used for counting and speed detecting in industrial automation and controlling sector.
Magnetic metal parts will periodically enter the sensor detection area during device operation. After that, the sensor will output a high-level pulse signal corresponding to device operation frequency in order to be functioned with counting and speed detecting.
GMR sensors detect magnetic metal parts through inner Hall components. When components to be detected reach closer to the sensor detection region, the sensor will convert the detected signal into an electrical signal and output it.
