1:Brief Introduction
SM 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.
2:Features
Wide mains voltage range 
                    High frequency Long service life, compact volume, and 
                    convenient mounting 
Directly connect to transistor and 
                    logic circuit port like,
