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. 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. Combined 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.


Features and Benefits: (1)Anisotropy of magnetoresistance (AMR) Technology;(2)Wide range supply voltages;(3)Large airgap tolerance;(4)Low saturation field;(5)Phase A and phase B analog output;(6)Excellent temperature stability;(7)High tolerance to external magnetic field interference;(8)RoHS & REACH compliant.


Applications:(1)Incremental or absolute encoder;(2)Linear or angular displacement encoder;(3)Magnetic scale and magnetic encoder.
