Benefits & Features Specifications


A slip ring can be used in any electromechanical system that requires unrestrained, continuous rotation while transfer power or data from a stationary to a rotating structure. A slip ring is also called a rotary electrical interface, collector, swivel or a commutaor. A slip ring Can improve system performance by simplifying operations and eliminating damage-affected wires dangling from moving joints

LPR-4H Series high current slip ring provided routing space for hydraulics, pneumatics or a concentric shaft mount. The LPR-4H uses advanced fiber brush technology which offers several advantages over conventional slip ring contacts including multiple points of contact per brush bundle, low contact force per fiber and low contact wear rates. In addition, fiber brushes do not require lubrication and produce virtually no wear debris.
