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.
The main application field is in cars, i.e. as a breakerless trigger in electronic ignition systems.
Numerous industrial applications can be found in control engineering, especially in those areas
where switches must operate maintenance-free under harsh environmental conditions (e.g.
rpm sensor, limit switch, position sensor, speed measurement, shaft encoder, scanning of
coding disks, etc.).

Application Notes
The output current of the "open collector" must be limited to the maximum permissible value
by a load resistor adapted to the application.
For optimum efficiency of the integrated overvoltage protection, it is suggested that a resistor
of approx. 100 Ω be provided in the component's power supply to limit the current.
