An apparatus for transmitting binary information between a first device carried by a first body and a second device carried by a second body, movable with respect to the first body along a path within a given range of movement, includes at least one first electrically conductive main plate on the first body along the path of the second body and a second electrically conductive main plate on the second body. The first and second main plates remain opposite each other, at a constant distance from each other, when there is a relative movement of the second body with respect to the first body within the range of movement along the path, such that the first and second main plates form a main capacitor with a constant capacitance. Transmission of information from one of the first and second devices to the other occurs by coding the information into at least one binary coded signal, transmitting the coded signal by applying the coded signal to one of the first and second main plates of the main capacitor, collecting a received signal at the other of the first and second main plates of the main capacitor, and decoding the received signal.
