In summary, the KMT32B is a magnetic field sensor based on the anisotropic magnetoresistance (AMR) effect. AMR measurement technology uses a magnetic field to transform mechanical motion into an electrical signal. This technology is primarily used in rotational applications but can be used to measure linear motion also. Measurement Specialties KMT32B features a high signal-to-noise ratio giving it excellent sensitivity, immunity to EMI, and is stable up to temperatures of 160°C.
