A device for non-contacting transmission of electrical signals between one part moving relative to another part has at least one strip conductor pair for symmetrical signal transmission attached on a first of the two parts, in which strip conductor pair the electrical signals are supplied from a transmission module for differential signal transmission. At least one reception element is attached on the other of the two parts, at a slight separation along at least one segment of the strip conductor pair, and is connected with a reception module. The strip conductor pair is provided with one or more components for reduction of a common mode signal component that arises therein due to the differential signals therein. Additionally or alternatively, compensation elements for adaptation of a time offset between signals on the output conductors are arranged in the output conductors of the transmission module that minimizes the common mode signal component. A reduced electromagnetic perturbing radiation is achieved with the device during the non-contacting signal transmission by capacitive RF coupling.
