Material: Precious Metal + Engineering Plastic 360-Degree Rotating Interface: The rotating contact surface is gold-gold, and the precious metal contact guarantees a long working life. The stator and rotor circuits use colored conductors to make the circuit connection easier, and the 360° smooth and unrestricted rotation fully meets the image and data transmission. Good stability:Compact structure, low torque, compatible with data bus protocol Application:Electrical connectors, mechanical accessories. It has a wide range of uses and can meet the requirements of various industries.
