Product Details


Inner hole 33mm 30A  through hole slip ring---BTH3392-0330

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A standard through hole slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Its inner part rotates with a rotating shaft pass through the inner hole, so we call it “ through hole slip ring”   It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints
