APS12625LLHALT-AFP
Product Description
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for use with ring magnets. Featuring integrated vertical and planar Hall elements with orthogonal sensing axes, they provide inherent 90 phase separation independent of magnet pole spacing and air gap, eliminating the need for target optimization. These devices offer flexibility with XY, ZX, and ZY orientation 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/pulses.
