AMR4050 Datasheet | MultiDimension

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 pensates 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. The relative displacement of the sensor and the scale can be accurately determined by calculating the two sets of analog voltage signals. The AMR40X0 series have been designed with internal sensor elements close to the surface of the package to reduce limitations on airgap. bined with the already small DFN12L (6 mm × 2 mm × 0.75 mm) package, the AMR40X0 series give greater responsibility to system design and ease of assembly in tight spaces.
