A1181ELHLT-T Datasheet PDF - Allegro MicroSystems

Description
The A1180, A1181, A1182, and A1183 devices are sensitive, two-wire, unipolar, Hall effect switches. The operate point, BOP, can be field-programmed, after final packaging of the sensor and placement into the application. This advanced feature allows the optimization of the sensor switching performance, by effectively accounting for variations caused by mounting tolerances for the device and the target magnet.
