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 a digital voltage signal.
– Compact volume
– high precision of repeated location
– Diversified exterior structures
– Good performance of anti-interference.
– Many output forms
– High on-off frequency
– Wide voltage range
– Dust proof,vibration proof,water proof and oil proof.
– With short-circuit protection and inverted connecting protection.
– Long service life
