Abstract
A device includes a first and a second part, relatively rotatable, and data transmission structures for contactless transmission of data. The data transmission structures include a transmit and/or receive facility a coupling facility on the two parts. The transmit and/or receive facility extends over a small angle and the coupling facility extends over a complete circle. Data is transmitted between the facilities at a transmission frequency. The two parts include walls encompassing a tunnel interior space extending completely around the axis of rotation. The data transmission structures are arranged in the tunnel interior space. The walls are electrically conductive structures reflecting electromagnetic alternating fields in the transmission frequency range. An absorber structure is arranged at least on a part of the walls toward the tunnel interior space and the absorber structure absorbs electromagnetic alternating fields in the range of the transmission frequency.
