Honeywell Omnipolar Digital Hall-effect Sensor ICs

Honeywell Omnipolar Digital Hall-effect Sensor Integrated Circuits (ICs) are compact digital sensors that detect magnetic fields from either a north or south pole, simplifying installation. These sensors include reverse polarity protection and are available in three package styles for different mounting requirements. The Omnipolar sensor ICs operate within a temperature range from -40°C to +150°C and support a minimum supply voltage of 3Vdc. These RoHS compliant sensors are available in the SS351AT, SS451A, and SS551AT series, with a typical operating point of 85G at 25°C. Typical applications include motion control, proximity sensing, printer head position sensing, flow-rate sensing, and robotic control.
