below the plastic surface of the front side and is concentric towards the adjusting marking on the rear. The chip carrier is non-magnetic. The position sensor KSY 10 is particularly suitable for sensing the position of magnets and of softmagnetic material, resp., if the sensor itself is mounted on a magnet.
