A New Generation of Contactless Magnetic Position Sensors

Magnetic position sensors have several advantages which make them attractive for automotive applications: they are contactless (there is no mechanical wear-out), insensitive to dirt, low cost and MMT has been a leader in the development of solutions based on measurement of magnetic field amplitude using Hall effect. In this paper, we will present a new generation of sensors using recently developed angular position sensors which measure the angle of the magnetic field generated by a diametrically or sinusoidally magnetized magnet, with a focus on through shaft 360 degrees, angular sensors and linear sensors adapted to large displacements [10 ... 200 mm].
