Abstract: The invention relates to a safety system (1) for a separating protective device with a first monitoring device for monitoring whether the separating protective device is bolted with a bolting system and with a second monitoring device for registering the position of the separating protective device. The second monitoring device has a sensor that generates direction-dependent signals and that differs from the first monitoring device.

Abstract: The invention relates to a safety switch (2) with a redundant input structure and with a redundant output structure. The safety switch (2) is designed for integration into a series connection (1) of safety switches (2); the safety switch (2) has devices for detecting and adjusting the operating mode in the series connection (1). The safety switch (2) is designed for replacement in the series connection (1) during its operation.

Abstract: The invention relates to a module arrangement (1) with a base module and at least one submodule (5); the base module has at least two connection modules. The submodule (5) can be put into contact via a connection module with a choice of one of the connection modules of the base module and can consequently be attached to the base module in different orientations. Detection devices for detecting the orientation of the submodule (5) attached to the base module are provided in the base module.

Abstract: A clamp for arrangement on a carrying arm is described. The clamp has a first and a second clamp half (10, 20) with in each case two lateral angle pieces (12; 21 ), in which are located a hole (14; 23) for positioning the clamp halves (10, 20) on the carrying arm, whereby the angle pieces (12, 21) which are directed against each other lie pairwise against each other and in each case one angle piece (21) of each clamp half (10, 20) lies on the inside and the other angle piece (12) of the same clamp half (10, 20) lies on the outside, and a legged spring (4) which lies between the clamp halves (10, 20) and keeps the clamps (3) closed. The internal angle piece (21) of one clamp half (10; 20) interlocks rotatably with the external angle piece (12) of the other clamp half (20; 10), and the legged spring (4) fills, in axial direction, the space between the internal angle pieces (21) in each case of the clamp halves (10, 20).
