Abstract: Disclosed herein is an electrical connector for transferring electrical power and data through mating with another electrical connector. The electrical connector comprises an insulating connector housing presenting a mating interface, wherein the mating interface extends in a first plane. The electrical connector further comprises a contact arrangement comprising a plurality of electrical contacts extending at least partially normally to the first plane. The plurality of contacts comprises one or more first pair of electrical contacts arranged to transfer power. The plurality of contacts further comprises one or more second pair of electrical contacts arranged to transfer data, wherein each one or more second pair comprises a receiving contact and a transmitting contact. Each electrical contact in a pair is located symmetrically to the other electrical contact of the pair with regards to a second plane normal to the first plane.
