Being highly resistant against electromagnetic interference, our ROTOCAP capacitive slip rings ensure a reliable high-speed data transmission even in environments with strong electric and magnetic interference. In wind turbines, our capacitive transmission link ensure a reliable transfer of data between any BUS-systems. They also ensure the real-time transfer of measuring and control signals provided by the various sensors currently used in rotor blades. Our capacitive slip rings are also used in medical systems, automation industry, radar and surveillance systems as well as offshore and marine applications. Applications Our ROTOCAP slip ring technology facilitate uni- and bidirectional high-speed data transmission between rotating and stationary parts with up to Gigabit Ethernet rates. The data transmission is based on a non-contacting capacitive transfer technology. Due to the innovative electronics design for the capacitive transfer, the non-contacting link can be designed to very compact dimensions while maintaining a high level of robustness. The patented technology allows high-speed data transmission at extremely low bit error rates better than 10-12. In addition, ROTOCAP slip rings are highly resistant against external interference. The design of the capacitive slip rings is modular, thus allowing a simultaneous and bidirectional use of multiple channels. All standard DC-free protocols such as Fast Ethernet, Video or Fibre Channel can be transmitted.
