LPR-4H Series Slip Ring


LPR-4H high Current slip ring provides 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.
