Abstract

The invention relates to an inductive rotary joint having at least two component parts which each comprise a coil for introducing power and/or taking-up power. In order that the rotary joint may be able to withstand even high mechanical load, at least one of the component parts is made of a synthetic resin containing soft magnetic particles, and the coil of the one part is at least partially located in the synthetic resin.
