Unipolar Hall Effect Magnetic Switch Sensor With Open Collector Output In Compact SOT-23-3 Package

The SS349RT Magnetic Switch Unipolar Open Collector Hall Effect Sensor is a compact magnetic sensing IC designed for reliable contactless position detection and magnetic switching applications. Built using Hall-effect sensing technology, this unipolar magnetic switch responds specifically to a north magnetic pole and provides a stable open-collector digital output suitable for embedded systems, industrial automation, consumer electronics, and motion-control applications. Its miniature SOT-23-3 package enables efficient integration into compact PCB layouts and portable electronic products.

The SS349RT offers lower magnetic sensitivity with a typical operating point of 305 Gauss at 25 degrees C, making it suitable for applications requiring stronger magnetic field detection and improved immunity to stray magnetic interference. Designed for low-voltage and energy-efficient operation, the sensor supports compact embedded designs and battery-powered systems. Its contactless sensing operation eliminates mechanical wear, improving long-term durability and system reliability.
