Slip rings
A slip ring is a component for transmission of power and data signals to a freely rotating unit such as a radar aerial or the rotor blades of a wind turbine. Also called a slip ring device, rotary electrical joint, collector, or electric swivel, a slip ring can be used in any mechanical device that requires free rotation while transmitting power or electrical data signals. Slip rings can improve the performance and simplify the design of many applications.
Are you looking for a slip ring for transmission of optical signals? See Fibre-Optic Rotary Joints/FORJs.
Penlink also offers a large range of slip rings combined with other rotary joint solutions: electrical slip ring with a coaxial rotary joint (RF), electrical slip ring with a fibre-optic rotary joint (FORJ), electrical slip ring with an air swivel, and electrical slip ring with a hydraulic swivel.
