High Sensitivity Latching Digital Hall-effect Sensor For Brushless DC Motors And Magnetic Position Detection
The SS360ST High Sensitivity Latching Digital Hall-effect Sensor is a compact and highly responsive magnetic sensing device designed for applications requiring reliable detection of alternating magnetic poles. Activated by a south magnetic pole and reset by an opposite magnetic field, this latching Hall-effect sensor provides consistent switching performance for brushless DC motor commutation, rotational speed measurement, and position sensing applications. Its high magnetic sensitivity of 30 G typical and 55 G maximum enables accurate operation with low-strength magnetic fields and compact magnet assemblies.
Built in a space-saving SOT-23-3 surface-mount package, the SS360ST delivers fast response times by eliminating chopper stabilization, resulting in cleaner output signals and improved magnetic switching performance. The sensor supports a wide operating voltage range from 3 VDC to 24 VDC and maintains stable operation across temperatures from -40 C to +150 C. Reverse polarity protection and reliable switching characteristics make it well-suited for industrial automation, consumer electronics, motor control systems, and compact electronic designs.
