Phares UMS03-01 Ultra Mini Hall Effect Sensor w/5/16-24 2.0" Thread, 5-24VDC w/Sinking NPN Square Wave Output & 1 Ft Cable

Call for Price

The Phares UMS03 Digital Output Hall Effect Sensor switches logic low ("0") when the magnetic field strength at the sensor face exceeds the hall effect operate point threshold, and switches logic high ("1") when the magnetic field strength falls below release point threshold. The difference in the magnetic operate and release points is the hysteresis of the Hall Effect Sensor. This built-in hysteresis allows clean, fast switching of the output, even in the presence of external mechanical vibration and electrical noise. The omnipolar operation allows activation with either a north or a south polarity field of sufficient strength. In the absence of a magnetic field, the output is off.
