Abstract: An interlocking device for locking a movable safety guard has a locking unit, an electric mover, an additional release unit, a sensor device and an evaluation unit. The locking unit is movable between a locking position for interlocking the movable safety guard and a release position for releasing the movable safety guard and the mover is configured to move the locking unit between the locking position and the release position. The additional release unit is movable from a neutral position into an additional release position to move the locking unit from the locking position into the release position. The sensor device is configured to detect a position of the locking unit and a position of the additional release unit. The evaluation unit is configured to output a locking signal, a normal release signal, and an additional release signal.

Abstract: A safety switch for monitoring an access of an automation system includes a stationary part and a movable part. The safety switch has a first housing part having an elongate shape and a second housing part having a shape form-fitted with respect to the first housing part. The first housing part and the second housing part each have magnets. The first housing part is arranged in a fixed position in the stationary part of the access and the second housing part is arranged in the movable part of the access such that the magnetic elements are located opposite one another in a closed state of the access, the magnetic elements are magnetically effective together with one another, and a magnetic retaining force can be measured. The first housing part has a signal receiver and an evaluation unit and the second housing part has a signal transmitter, or vice versa.
