Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer flexible 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 and allows for design changes without sensor repositioning. The devices are available in XY, ZX, and ZY orientations and feature a unique power-cycling restore function (-P option) to prevent lost counts/pulses. The APS12625 provides Speed and Direction outputs, while the APS12626 offers Quadrature outputs (Channel A/B).
