Slip rings can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotating structure. It is also called a rotary electrical interface, Slip Ring Assemblies, Rotary Connector, Slip Ring Units.It can improve electromechanical capability, simplify system design, eliminate possible damage while rotation. Itâ??s the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument.
