LPKS-0205 Pancake Slip Ring with Through Bore 46.0mm


A slip ring can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure.
The 46.0mm unobstructed through-bore provides routing space for hydraulics, pneumatics or for a concentric shaft mount. The LPKS-0205 Pan Cake Slip Ring 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.

◆ Transfers control and data signals
◆ Fiber brush technology provides maintenance-free operation (no lubrication required)
◆ Modular design meets special requirements through off-the-shelf manufacturing techniques
◆ Customized configurations for your application
