Title Capacitive Slip Ring - ROTOCAP Description - Non-contacting high-speed data transmission - Data transmission rates up from 50 Mbit/s to 1.25 Gbit/s - Bit error rate < 10^-12 - High resistance against EMI and ESD - Compatible with all standard transmission protocols - Suitable for integration into other slip-ring systems - Suitable for combination with rotary joints for media - Compact design with free inner bore - Diameters up to 500 mm available 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.

Title Fiber Optical Rotary Union - ROTORAY Description - Very low insertion loss - Extremely robust design - Optical performance insensitive to temperature changes - Single Mode or Multi Mode version available - Data transmission rates up to 30 Gbit/s - Immune against EMP and ESD - Easily upgradeable to multichannel system Our Fiber Optical Rotary Union (FORU) Rotoray® supports contactless high speed bi-directional data transmission through a single fiber between a stationary and a rotating part. It is available for single- and multimode glass fibers. The core technology of this device is a wave length optimized micro lens collimator and high precision bearing system. Our new developed ultra precise alignment process and innovative technology of positioning the optical components results in outstanding optical efficiency. The robust stainless steel design insures nearly unchanged insertion loss even under severe temperature or vibration conditions. The compact stainless steel housing is dust and water tight and made for harsh environment applications. The whole unit is maintenance-free. This FORU is a passive device that will work with any data transmission protocol and can be used for highest data rates up to 30 Gbit/s. The fiber connectors are usually FC/PC or FC/APC, but others are available as well. PDF Click here to download PDF Category Electro-Optics Fibre Optic ROVs Slip Ring Systems

Title Hybrid Slip Ring Description - Electrical power-, signal- and data transmission - Optical data rates up to 30 Gbit/s - Air channel for 250 bar - Gold/Gold technology insures highest contact quality - Robust offshore connectors - Seawater resistant aluminium or stainless steel design - Reliable under high vibrations and extreme temperatures This slip ring was developed specifically to meet the requirements of the seismic industry. The unique design of our Rotoflux slip ring insures the reliable transmission of gun control signals and sensor signals from the hydrophones with very low noise. For the rapidly increasing frequency bandwidth we have integrated a multi channel optical rotary union with single mode fibres. The very compact design allows an easy integration into different style winches. The robust housing guarantees a reliable operation in rough conditions and most extreme environments on a vessel deck. All our design ideas are focused to enable our customers to run their seismic vessels most effective.

Title Rotary Transmission System - ROTOKOMBI Description - Combination of electrical slip rings and also with rotary unions for media supply - Simultaneous transmission of current, signals and media such as air, water, oil, coolant, grease, vacuum, etc. at high or low speeds - For all media with the most different pressures and volume flows - Optimally adjusted, reliable transmission - Low-maintenance sealing systems - Maintenance-free slip ring systems - Very simple to adapt to plant or machine Rotokombi systems allow the combination of different rotary unions as well as the combination of rotary unions and slip rings. This technology makes it possible to transmit several mediums with different pressures and electrical currents and signals simultaneously between stationary and rotating machinery parts. The Rotokombi technology ensures that for every medium the optimally adapted sealing system is applied. Proven systems and tested components are used that are assembled specifically for every application according to customer requirements. This system allows the combination of the features of the slip ring variants Rotoflux, Rotoray and Rotocap with any imaginable features of rotary unions, creating complete rotary transmission systems from one single source.
