Murata AMR magnetoresistive sensors

Murata AMR sensors comprise four AMR elements and IC an IC circuit to detect changes in the resistance of a magnetoresistive element that is affected by an external magnetic field. This is achieved from a thin film ferromagnetic NiFe alloy that is deposited over the IC circuit. Murata offers more than 5 models that support a broad range of applications.
