Allegro MicroSystems A1185
The A1185 and A1186 are ultrasensitive, 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.
