SLIP RINGS CAN BE USED IN SYSTEMS requiring the transmission of electrical power and/or signals from a stationary to a bidirectional, intermittent, or continuously rotating structure. A slip ring is also called a rotary electrical interface, collector, swivel, or rotary joint. The SR130 series uses nickel-plated beryllium copper brushes and nickel bronze rings for power circuits and auxiliary signals; golden beryllium copper brushes and golden bronze rings for networks such as CAN and Profibus.

The SRST130 version is IP67-rated and therefore suitable for outdoor use and underwater environments. It is also available for marine environments. The SREX130 version is Atex-certificated and fit for use in explosion-prone areas for gas (Zone 1: II 2 G) or dust (Zone 21: II 2 D).
The series is also used for applications requiring transmission of networks, such as CANopen, Profibus, Devicenet, Ethernet, Ethercat, Profinet, and others. When an absolute reliability in the transmission of high frequency or data rates signals is needed - even on multiple channels - FORJ (fiber optic rotary joints) can be integrated.

Typical applications of the product are oil plants, cable reels, the inspection of pipes and cargo ships, bottling of gases and liquids, food machinery, pharmaceutical and medical equipment, water treatment, printing machines, as well as silos. Normally this series is supplied with 300-mm multicore cables. The versions for fieldbuses are supplied with CAN, Profibus, etc. cables (up to 12 Mbit/s). The standard IP67 version is supplied with an anti-condensation filter.
