Safety guard locking devices

Balluff guard locking switches assure that when moveable protective devices such as guard doors or flaps are not properly closed, the machine cannot be started up. The Balluff devices, however, are also designed so that they can compensate for a certain amount of offset (e.g. when doors settle or are imprecisely aligned).

Due to RFID monitoring, non-contact transponder-coded guard locking devices are especially good at protecting against tampering. Transponder-coded safety sensors achieve high anti-tamper protection because the RFID transponder is uniquely identified by the sensor. The sensors are also insensitive to vibration and mechanical play in the protective devices.

Electromechanical Guard Locking Devices

For the electromechanical versions, the special shape of the mechanical mating component significantly reduces the risk that the safety function can be defeated. The mechanical contour of the insertion opening for the switch head also compensates for any mechanical play in the protective device.

Balluff offers you complete safety solutions in which all the safety components are precisely matched to each other. Connection is simple and cost-efficient, using standardized M12 connection technology.

As is the case with all Balluff safety components, the safety guardlocking devices can also be directly connected to the Safety over IO-Link module, which bundles all signals and forwards them via an IO-Link master module to the safety controller. As a bonus, you benefit from all the advantages of an intelligent Industry 4.0 solution.
