Description
A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. SenRing offer a full line of standard products for a wide variety of applications, as well as complete specialized rotating solution & rotate joint design & build services.
SNH025 can be used in any electromechanical system that requires unrestrained, intermittent, or continuous rotation while transferring power or data.The 25.4mm unobstructed through-bore provides routing space for hydraulics, pneumatics or for a concentric shaft mount and a compact 86mm outside diameter for restricted space applications.
The SNH025 uses SenRing's 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.The precious metal contacts are maintenance free and provide long life.
