Overview 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.
It is easy to obtain the highest level of safety for the electrical part with the dual interlock actuator and the two OSSD outputs, but an ABB bolt- or rotary-handle accessory for MKey RFID is recommended to meet the mechanical requirements of relevant safety standards.

Installation and maintenance Installation The installation of all ABB Electrification safety dual interlock switches must be done in accordance with a risk assessment for the individual application. Installation must only be carried out by competent personnel and in accordance with these instructions.
62061, to confirm that all the safety functions are working properly. Warning! In case of breakdown or damage to the product, contact the nearest ABB Electrification Service Office or reseller. Do not try to repair the product yourself since it may accidentally cause permanent damage to the product, impairing the safety of the device which in turn could lead to serious injury to personnel.
Minimum safety distance When using interlocking guards without guard locking to safeguard a hazard zone, the minimum allowed safety distance between the guarded opening and the hazardous machine must be calculated. To ensure that the hazardous machine motion will be stopped before it can be reached, the minimum safety distance is calculated according to EN ISO 13855 (“Positioning of safeguards with respect to the approach speeds of parts of the human body”).
Where the Risk Assessment for the application permits, non-latching escape release versions of the MKey RFID series enable quick release of the switch lock in case of emergency. The switch can be mounted such that access to the release button is available from inside the active guard area.
Disassembly and disposal Disassembly The MKey RFID dual interlock device with guard locking must be disassembled in its de-energised state, no power. Disposal The MKey RFID dual interlock device with guard locking must be disposed of in accordance with the national legislation and regulation. 2TLC010088M0201 Rev.A...
