These Hall-effect switches are designed for magnetic actuationusing a bipolar magnetic field, i. e., a North-south alternatingfield, and they are designed to operate continuously over extendedtemperatures to 150° They combine extreme magnetic sensitivity withexcellent stability over varying temperature and supplyC, Voltage.The high sensitivity permits their use with multi-pole ring magnetsover relatively large distances.

Each device includes a voltage regulator, quadratic Hall voltagegenerator, temperature stability circuit, signal Amplifier, Schmitttrigger, and open-collector output on a single silicon chip. Theon-board regulator permits Operation with supply voltages of 4.5 to24 V. The switch output can sink up to 25 mA. with suitable outputpull up, They can be used directly with bipolar or MOS logiccircuits.
