The Hall-effect vane switch HKZ 121 is a contactless switch consisting of a monolithic integrated Hall-effect circuit and a special magnetic circuit hermetically sealed in a plastic package. The switch is actuated by a soft-iron vane which is passed through the air gap between magnet and Hall sensor.
