Revolutionary technology…
Electrical slip rings allow an electrical link between a stationary and a rotating part, where multiple rotations and transmission by cable would be impossible.
• Standard or customized with or without bore
• Transmission of low level signals or high frequencies up to 500 MHz
• Transmission of signals: video, RS 422, RS 485, Profibus, land network, CAN Bus, Ethernet
• Transmission of power signals up to several hundreds of amperes
• Every dimension: from a few millimetres to several metres, open or sealed versions
• Suited to all environments with adapted materials and protection: spatial, defence, nuclear, robotic, medical, food industry, wind energy
• Need little to no maintenance using precious metal technology (up to several hundred million rotations without changing components)
• Can be used with all types of rotary joints: pneumatic, hydraulic, hyper-frequency or optical joints...
