Position and limit sensing

Operate
Basic principle

The sensor is in a normally open position. When the plunger is depressed the magnetic circuit will be complete, activating the Reed Switch to close its contacts sending a voltage output to the customer electrical interface.

Connection options

Customized to customer choice of connection system.

Packaging Options

Custom packaging can be provided to meet any need, please contact KESENS Engineering for details.
