    Tips: What is the role of a rotary union?

    1. 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.
    2. The rotary union improves system performance, simplifies system construction, and prevents damage to the wire during rotation.
    3. Electrical rotary unions accurately transmit Ethernet, USB, RS, CANBus, FireWire, servo motor signals, encoder signals, strain gauge signals, thermocouples and other signals


    Existing reviews of 6-Passage Rotary Union, Pneumatic/Electrical Slip Ring for Air/Water/Hydraulic
    Good conduction effect, economical and practical, worth buying
    Due to the equipment layout in factory, space is not enough. I used this rotary joint to transform the automatic retractable hot air gun reel, got a good effect, sliding is smooth, with 1000 watt heating wire is no problem.
