Product Overview

The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They offer 2D magnetic sensing with vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap. This eliminates the need for target optimization, making them highly flexible. The APS12625 provides Speed and Direction outputs, while the APS12626 features quadrature outputs. A unique power-cycling restore feature (-P option) helps prevent lost counts/pulses. These devices are automotive grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V.
