AMR Linear Position Sensor (Pitch: 2 mm)

iC-SM2L is a linear position sensor which operates on the AMR effect (anisotropic magneto resistance) and has been designed to work with magnetic scales which have a N/S pole pitch of 2 mm.
The amplitudes of the differential output voltages are largely independent of the magnetic field strength and thus not sensitive to changes in distance.
iC-SM2L is resistant to strong magnetic fields and not sensitive to external homogenous magnetic fields.
