Overview

Moving a KMXP sensor along a magnetic scale will produce a sine and a cosine output signal as a function of its position.  In order to deliver satisfying results, this will be achieved as long as the air gap between sensor edge and magnetic scale surface does not exceed approximately half of the pole pitch. As the sensor principle is based on the anisotropic magneto resistance effect, the signal amplitudes are nearly independent on the magnetic field strength and therefore air gap variations do not have a strong effect on the accuracy. The sensor detects a magnetic gradient field and is thus almost insensitive to homogenous stray fields. Sensor components are available for 1mm, 2mm and 5mm pole pitch.
