Abstract
An apparatus for the monitoring of a protection region which comprises a monitoring unit for the detection of an object penetrating into the protection region is described. The monitoring unit has at least one output at which a control signal for the excitation of a device to be monitored, in particular a switching signal for the switching off of the device, can be produced when an object penetrates into the protection region. Furthermore, the apparatus comprises at least one connection for a switch, in particular for an emergency off switch, through which the device can be excited, in particular switched off. The connection is designed as input of the monitoring unit, with it being possible to generate the control signal for the device to be monitored at the output of the monitoring unit through actuation of a switch which is connected to the input.
