General description
MKey RFID interlock switches are designed to provide position interlock detection for moving
guards. It is designed to fit the leading edge of sliding, hinged, or lift off machine guards. The
actuator is fitted to the moving part of the guard and is aligned to the switch entry aperture. The
possibility to lock the switch in the protective position prevents unwanted access to machinery
until hazardous operations have ceased.
The locking is useful when applications include:
•
Processes which cannot be interrupted, such as welding.
• Machinery with a long stopping procedure, such as paper machinery that requires a long
braking operation.
•
Prevention of unauthorized access to a particular area.
