It is enclosed in a tubular plastic package with four tags. When operating the sensor with a constant supply current, the output Hall voltage is directly proportional to the magnetic field acting upon the sensor. This sensor is outstanding for its high inductive sensitivity and very low temperature coefficient. Data Sheet 1 1999-04-01 KSY 10 The Hall sensor’s active area is approx. 0.2 mm × 0.2 mm. It is placed approx. 0.35 mm 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.
