Dual hall effect sensor ALLEGRO APS12626LLHALT-BFP with flexible orientation support and quadrature output channels
Product Overview
The APS12625 and APS12626 are dual ultrasensitive Hall-effect latches designed for ring magnet applications. They offer flexible 2D magnetic sensing with orthogonal vertical and planar Hall elements, providing inherent 90 phase separation independent of magnet pole spacing and air gap. These devices simplify integration by eliminating the need for target optimization and support various orientations (XY, ZX, ZY). 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. These sensors are automotive grade, qualified per AEC-Q100, and operate from 2.8 to 5.5 V with high junction temperature capability.
