SM series Hall sensor is a kind of magnct-sensitve scnsor consisting of voltage regulator, Hall voltage generator, differential amplifier, Schmidt trigger and the output pole of collector open circuit. Its input is the magnetic flux density. The output is a digital voltage signal.
Features:
Wide mains voltage range
High frequency
Long service life, compact volume, and convenient installation
Directly connect to transistor and logic circuit pore like, TTL.MOS
