Rotary Union Installation Diagram

Tips: What is the role of a rotary union?
- The main function of a electrical rotary union is to solve the problem of wire entanglement of the device in 360° rotation. During the electrical design process, it is needs to connect the wires to the rotating parts. When the mechanical part is continuously rotating at 360° without restriction, there will be a wire entanglement problem. To ensure that the current or signal can be accurately transmitted to the rotating component, an electric rotary connector (commonly known as an electric rotary union or rotary joint) is required to transmit the rotational connection of power and signal.
- The rotary union improves system performance, simplifies system construction, and prevents damage to the wire during rotation.
- Electrical rotary unions accurately transmit Ethernet, USB, RS, CANBus, FireWire, servo motor signals, encoder signals, strain gauge signals, thermocouples and other signals
6-passage pneumatic rotary union affordable price. It can transmit compressed air, steam, vacuum, hydraulic and other fluid medium in 360 ° rotation. Electrical slip ring also can select 12/24/36/56 wires 2A or 12/24 wires 5A for signal/current transmission. Thread port is G1/8" for 6~8mm pipes. Combinations of circuits and transmission current for customization.
