Abstract
A rotary joint includes a first part and a second part configured to rotate around a rotation axis against the first part. The first part has a first magnetic core, a sliding brush, and a capacitive data link component. The second part has a second magnetic core for coupling power with the first magnetic core, a sliding track for galvanic coupling with the sliding brush, and a second capacitive data link component to transfer data from and/or to the first capacitive data link component. To weaken magnetic stray fields from the magnetic core, the rotary joint is a disc-type rotary joint, and the sliding track is arranged radially between the second magnetic core and the second capacitive data link component.
