SS360NT/SS360ST/SS460S Hall-Effect Sensor ICs Honeywell High Sensitivity Bipolar Digital Hall-Effect Sensor ICs SS360NT / SS360ST / SS460S are small, versatile, highly sensitive devices designed to respond to alternating North and South poles. SS360NT is turned on by a North pole, SS360ST and SS460S are turned on by a South pole. This sensor IC does not use chopper stabilization, resulting in a clean output signal and fast latch response time. These devices are ideal for brushless dc motor commutation, speed sensing and RPM measurement, and medical equipment using motors.
