General Description
The Seat Occupancy sensor is a magnetically operated
push button sensor with a simple push-fit clip mounting
configuration, allowing the passenger safety system to
determine the presence of an object or person in a seat.
Applications
Seat occupancy
Position and limit sensing
Operation
Basic Principle
The sensor is in a pre-defined single logic output state. When the plunger is depressed, the magnetic circuit will be complete,
activating the Hall Effect sensor, which would switch logic (voltage) output levels to the customer electricalinterface.
