This unit can be used in any electromechanical system that requires unrestrained, continuous rotation while transferring power or data from a stationary to a rotation structure. It’s also called a rotary electrical interface, commutator, collector, swivel or an electrical rotary joint. It can improve electromechanical capability, simplify system design, eliminate possible damage while rotation. It’s the key apparatus of various precision rotary worktable, electric test instrument, manufacture and process control instrument. Feature: Transfers power and /or signal data reliably Extremely low electrical noise Durable, compact and low cost No maintenance Convenient to assembly Operating smoothly Precious metal contact ensures over-long lifetime Typical application: Industrial mechanic controlling center, indexing tables Magnet driver, processing control equipment Robotics, rotary sensors, urgent illumination equipment Producing and controlling equipment Exhibit / display equipment CCTV and wind turbine Aviation, military, marine and medical equipment
