The carbon brush holder for slip ring can be used in any electro-mechanical system that requires unrestrained, continuous rotation while transmitting power and / or data from a stationary to a rotating structure. The carbon brush holder for slip ring is also called rotary electrical interface, commutator, collector, swivel or electrical rotary joint. The brush adopt noble metal alloy material, Conducting ring Using a 900V-groove ring. It adopt multilayer noble metal alloy for plating dispose. Color-coded lead wires are used on both the stator and rotor for simplified electrical connections.
