Honeywell SS552MT omnipolar magnetoresistive sensor

SS552MT is a digital position sensor in an SOT-89 style surface-mount package with omnipolar magnetic action. The sensor has magnetoresistive material integrated on silicon and encapsulated in a plastic package. The integrated circuit provides a digital output in response to very low magnetic fields.

Though this signal is identical to our digital Hall-effect sensors, it can be achieved by magnetoresistive sensors at much greater sensor-to-magnet distances.
