Honeywell Sensing and Productivity Solutions SS5 Series Hall Effect unipolar magnetic switch, part number SS549AT. This digital unipolar switch features an open collector output and is housed in a SOT-89B package (TO-243AA, Variant), supplied on tape and reel. Designed for surface mounting, the SS549AT is optimized for applications requiring precise magnetic field detection, with a typical trip point of 39mT and a release point of 23.5mT. Its temperature compensation ensures stable operation across an extended temperature range of -40°C to 150°C. The device operates with a supply voltage from 3.8V to 30V, drawing a maximum supply current of 10mA and providing a maximum output current of 50mA. This component is suitable for use in automotive, industrial, and consumer electronics sectors where reliable magnetic switching based on south pole detection is critical.
