Honeywell Omnipolar Digital Hall-effect Sensor ICs (SS351AT, SS451A, and SS551AT) are small digital sensors that detect magnetic fields from either North or South poles, simplifying installation. These sensor ICs operate with a typical sensitivity of 85G at 25°C and support low-voltage applications. Available in three compact package styles, these sensors offer flexibility for various designs. The devices are RoHS-compliant and include integrated reverse polarity protection.
