General Description

The AMR40X0 series magnetic grate sensors integrate two push-pull Wheatstone bridges, each of which contains four high-sensitivity anisotropic magnetoresistance (AMR) sensing elements.

Such a design effectively compensates temperature drift to ensure high accuracy under wide temperature range.

As the AMR40X0 moves along the magnetic scale, sensor outputs two orthogonal sets of analog voltage signals (sine and cosine), the period of which corresponds to the scale’s magnetic pole pitch.
