Allegro Microsystems Surface Mount Hall Effect Sensor, SOT-23W, 5-Pin

Dual element devices are integrated circuits that contain two independent Hall-effect switches. The digital outputs are out-of-phase (quadrature) when interfaced with the proper ring magnet design. These quadrature signals can be processed to determine target speed and direction. Alternately, the A1232 and A1233 internally process these switch outputs into speed and direction signals.
