The Honeywell APS00B is a miniature surface-mount magnetic displacement sensor for linear, angular or rotary displacement, designed for magnetic saturating field sensing. It uses Honeywell's Anisotropic Magnetoresistive (AMR) technology and contains dual, saturated-mode Wheatstone bridges that produce quadrature sine and cosine output signals, giving an angular range of ±90° without additional components and up to ±180° with external components.
The document gives features and benefits, potential applications in transportation, medical and industrial sensing, absolute maximum ratings, a specifications table, figures for detection of relative motion, the electrical diagram, pinout and sensing element location, typical bridge outputs, common wiring diagrams, mounting dimensions, and an order guide listing the APS00B and APS00B-T13 tape-and-reel variants and the separate APS00A instrumentation amplifier.

It measures ±90° without additional components, and measurements of ±180° are possible with external components.
It typically requires only 5 V at 4 mA (20 mW) to operate, with a specified supply voltage range of 1 V to 12 V.
The sensor has a resolution capability of less than 0.05°, and the specifications table lists 0.05°.
It is supplied in a small 8-pin SO-8 surface-mount package on tape and reel.
