Bipolar Latching Digital Hall-effect Magnetic Sensor For Position And Speed Detection Applications
The SS361RT Bipolar Latching Digital Hall-effect Magnetic Sensor is a compact magnetic-field sensing device designed for reliable position, rotational speed, and proximity detection applications. Built with a digital output stage and bipolar latching operation, this Hall-effect sensor changes output state when exposed to alternating north and south magnetic poles, making it well-suited for motor commutation, rotary encoders, and magnetic switch systems.
Housed in a space-saving SOT-23-3 package, the sensor delivers stable performance with low power consumption and fast response characteristics. Its solid-state design eliminates mechanical wear, providing long-term reliability in industrial automation, consumer electronics, automotive systems, and battery-powered devices that require accurate magnetic field detection.
