It is described a slip ring (10) comprising at least one movable portion (10A) and one fixed portion (10B), at least one interface surface (10C) being defined therebetween, the slip ring (10) further comprising contactless transmission elements (12A, 12B) for a signal transmission, which are associated with the movable portion and fixed portion (10A, 10B), respectively, as well as at least one contact transmission element (13, 14) arranged at the interface surface (10C) and used only for a power transmission. Conveniently, the contactless transmission elements (12A, 12B) comprise respective inductive coupling elements for a signal transmission by magnetic induction. |
