A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Slip ring can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints Wear-resisting (Silver to silver contacting) Good impact resistance Signal and current compatible Workable in hostile environment(-40℃>~ +100℃) Flexible design for special requirements
