Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. They feature orthogonal vertical and planar Hall elements, providing 90 phase separation independent of magnet pole spacing and air gap, eliminating the need for target optimization. These devices offer flexibility in orientation with XY, ZX, and ZY options. The APS12625 provides Speed and Direction outputs, while the APS12626 offers quadrature outputs (Channel A/B). A unique power-cycling restore feature (-P option) minimizes lost counts. They are automotive-grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V with high magnetic sensitivity and output short-circuit protection.
