The through-hole gas slip ring combined with a through-hole electric slip ring is a rotating connection device that integrates the functions of gas and electrical signal transmission. It allows for the simultaneous transmission of gas and electrical signals between rotating and stationary parts, widely used in rotating equipment that requires both pneumatic and electrical connections, such as robotics, automation equipment, medical devices, and other fields. The design of this slip ring aims to reduce system complexity and space occupancy, improving the reliability and efficiency of the equipment.
