1. A process media transfer unit for an industrial robot, comprising:

  • a first part for attachment to a first robot part, first part comprising a first electric circuit including a first aircored coil;

    a second part for attachment to a second robot part, the second part comprising a second electric circuit including a second aircored coil;

    an airgap formed between the first aircored coil and the second aircored coil, the first and second part being coaxially arranged about a common axis and separated by the airgap to provide an endless rotation relative to each other; and

    ,a magnetic circuit for interaction with the first electric circuit and the second electric circuits across the airgap, whereby the first electric circuit is arranged to receive an electric current to generate a magnetic flux in the magnetic circuit and the second electric circuit is arranged to receive the magnetic flux of the magnetic circuit and supply an electric current to the second robot part.
