The invention relates to a contactless connector (100), a system including the contactless connector (100) and a corresponding mating connector (200), and a manufacturing method for the contactless connector. In order to enable the contactless connector to transmit/receive power to/from the corresponding mating connector, the invention suggest providing at the contactless connector an inner ferrite element (102, 202) and an inductive coupling element (110) arranged to at least partially surround the inner ferrite element. An outer ferrite element (107, 207) of the contactless connector is arranged to at least partially surround the inductive coupling element (110), wherein a front end (108) of the outer ferrite element (107) facing the mating end of the contactless connector is recessed in an axial direction of the contactless connector with respect to a front end (103) of the inner ferrite element (102, 202) facing the mating end (101). A rear end (109) of the outer ferrite element (107, 207) is magnetically connected to a rear end (104) of the inner ferrite element (102, 202). An inductive coupling support element (601) is arranged around the inner ferrite core element (102, 202). The inductive coupling element (110) is formed from a wire wound around the inductive coupling support element (601) to form a coil comprising a plurality of coil windings (115). The connector further comprises an antenna element (402a) and an antenna connection line (701) arranged in an opening in the inner ferrite element (102, 202).
