Overview
HKZ 121 Hall-Effect Vane Switch Features q q q q q q q q q HKZ 121 Bipolar IC Contactless switch with open collector output (40 mA) Static switching High switching frequency Hermetically sealed with plastic Unaffected by dirt, light, vibration Large temperature and voltage range Integrated overvoltage protection High interference immunity Integrated capacitors for EMI protection P-HKZ-3-1 Type HKZ 121 Ordering Code Package Q67000-A9097-A401 P-HKZ-3-1 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 maintenanc...
