What is a Conductive Slip Ring?

A conductive slip ring, also known as an electrical rotary joint, is a device that allows power or signals to be transmitted during a rotating motion. It is mainly composed of a stationary part and a rotating part. The stationary part usually contains brushes (or brushes), and the rotating part contains a conductive ring. Through the contact between these components, the slip ring can stably transmit power and signals during rotation, and is commonly used in rotating platforms, robots, sensors, generators, automation equipment and other fields.
