Description

An electrical slip ring is a rotating assembly used to transfer power, signal or data from a stationary part to a rotating part. Also called a rotary electrical joint, collector, electric swivel or rotating connector. It can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power, signal and data.

A slip ring consists of a conductive circle or band mounted on a shaft and insulated from it. Electrical connections from the rotating part of the system are made to the rings. Fixed contacts or brushes run in contact with the rings, transferring electrical power or signals to the exterior, usually the static part of the system.
