2. What is a slip ring?

A slip ring is a vital electromechanical device that enables the transfer of power and electrical signals from a stationary platform to a rotating structure. A slip ring can be used in any electromechanical system or machine/equipment that requires rotation while transmitting the power or signals, such as those found in radar antenna, gun turrets, periscopes, electro-optic sensor gimbals, space satellites, and etc. Slip ring can excellently improve the mechanical performance inside the system, simplify system operation and eliminate damage-prone wires dangling from movable joints. In electrical design, if the mechanical parts need 360-degree unlimited continuous rotation, and the wire need to be connected to the rotating part, the electrical engineer needs an rotating electrical connector to avoid the wire twisting. This electrical rotary joint is called Slip Ring.
