Honeywell's omnipolar hall-effect digital position sensors operate from a voltage as Low as 3 Vdc and offer reverse polarity protection. These sensors can be operated by a North Pole or a South Pole, eliminating the need for the magnet polarity to be identified. The SS351AT is a subminiature SOT-23 surface mount device that is available on tape and reel. The SS451A is available in a leaded, flat TO-92 style package. Both types are very small, versatile sensors operated by the magnetic field from a permanent magnet or an electromagnet. Their thermally balanced integrated circuit provides stable operation over a wide temperature range.
