Abstract: In order to improve a sensor comprising an emitting element emitting a bundle of light rays in a direction of propagation, a receiving element receiving the bundle of light rays and having at least one receiving surface for the bundle of light rays, and an evaluating device generating an output signal of the sensor, such that exact determination of the deflection and the direction of deflection is possible, it is proposed that in each deflection position, a receiving surface be illuminated by only a partial bundle of rays of the bundle of light rays in the direction of deflection, that the receiving element generate for the receiving surface an integral intensity signal corresponding to the total intensity impinging upon this receiving surface and that the evaluating device detect the intensity signal and determine the deflection with a processor.

Abstract: In order to provide an optical signal transmission line for transmitting, for example, control, regulating and monitoring signals between units of a technical device, comprising a connection element adapted to be detached from the units and a light wave guide leading away from this connection element for transmitting optical information, which does not have the aforementioned disadvantages of the known detachable connection elements for light wave guides, it is suggested that the signal transmission line operate optoelectronically in that the connection element detachable from the units comprises a detachable electrical connection serving to provide a detachable connection between the signal transmission line and one of the units, that the connection element comprise a transformation unit arranged between the electrical connection and the light wave guide for converting electrical into optical signals and vice versa, and that the connection element keep the electrical connection, the transformation unit and t
