Failure to comply with these instructions could result in death or serious injury. Sensing and Control SS552MT Series 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 magneto-resistive sensors at much greater sensor-tomagnet distances. Surface-mount packages are mounted directly on the electrical traces on the PC board and attached by an automatic solder reflow operation which requires no holes, so it reduces the cost of the PC board. These packages are supplied on tape and reel and can be automatically placed on PC boards by use of pick-and-place equipment. SS552MT Series is operated by magnetic fields (North or South) parallel to the sensor package. NOTE: Due to the inherent high sensitivity of these sensors, stray magnetic fields which are parallel to the IC may affect operation.
