Abstract: The invention relates to a relay, having an electromagnetic drive with a field coil arranged around an iron core which defines a plane, and a yoke. The electromagnetic drive works together with a movable armature which can switch a movable electrical contact via an actuating arrangement. The relay is accommodated in a housing, wherein an intermediate base and/or partition is included between the electromagnetic drive and the contact. The electromagnetic drive is arranged on one side of the partition, and the movable electrical contact is arranged on the other side of the partition. The partition has an opening through which the mechanical actuation of the contact is carried out. Because the armature is pivotable about an axis of rotation perpendicular to the plane of the iron core, the relay can have a lower constructed height than a conventional relay.

Abstract: A device includes a sensor and an actuator. The sensor has a receiving circuit with a sensor and a detector, as well as a computer connected to the detector. The sensor cooperates with the actuator to generate a first receiving circuit signal during a normal operation when a switching distance between the sensor and the actuator is undershot. The detector generates a first output signal as a function of the first receiving circuit signal, and to transmit transmits the first output signal to the computer. The receiving circuit includes a signal emulator and a switch-over element. The signal emulator generates a second receiving circuit signal during a test operation. The detector generates a second output signal as a function of the second receiving circuit signal and transmits the second output signal to the computer. The device can repeatedly switch between normal operation and test operation.

Abstract: A device for detecting objects in a monitoring range is described, comprising a sensor and an emitter, wherein the emitter includes the following components: a housing, a radiation source for emission of electromagnetic rays and a radiation-conducting device, which is designed to conduct the rays on their path from the radiation source to the point of exit from the emitter, wherein the radiation-conducting device has a focusing element for focusing the rays. The radiation-conducting device is designed to deflect the rays on their path from the radiation source to the point of exit from the emitter by two reflections.

Abstract: The invention relates to a method for evaluation of signals from a LED status indicator of a device, in particular a safety device, comprising the steps detecting a signal emitted by the LED status indicator by means of a camera of a portable evaluation device, comparing the detected signal with signals stored in a database, wherein a status is associated in each case with the stored signals in the database, displaying information about the status which is associated with the detected signal by means of a display means of the portable evaluation device, wherein the emitted signal in the form as emitted by the LED status indicator is not distinguishable or not unambiguously distinguishable by the human eye from other signals which can be emitted by the LED status indicator.
