Application: 
LM series Hall sensor is a kind of magnet-sensitive sensor 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 adigital voltage signal. 

Features 
Wide mains voltage range: High frequency, Long service life, compact volume, and convenient mounting 
Directly connect to transistor and logic circuit port like, TTL. MOS
