Electrical Rotary Joint (Slip Ring)
Powering Continuous Rotation. Essential electromechanical devices that enable continuous, unrestricted rotation while maintaining secure and stable electrical connections.
Asian Tool Slip Ring
Uses a liquid mercury contact interface for continuous rotation, delivering ultra-low electrical noise and near-zero contact resistance with no maintenance required.
Capsule Slip Ring (SRC Series)
Compact, barrel-shaped unit; self-contained and typically handles low current and high-speed signals.
Through Bore Slip Ring (SRH Series)
Features a hollow center for routing hydraulic lines, pneumatic lines, or a drive shaft.
Miniature Slip Ring (SRM Series)
Extremely small size with low torque and low electrical noise. Ideal for fine instruments.
Ethernet Slip Ring
Specifically designed and shielded to reliably transmit high-speed 100BASE-T or 1000BASE-T data signals.
Pin Type Slip Ring (SRP Series)
Simple, modular design where contact is made via pins pressed against a groove or track.
Pancake Slip Ring (SRP Series)
Flat, disc-shaped structure; rings are concentric on a flat plane. Very short axial length.
Customized Slip Ring (SRT Series)
Tailored to meet specific performance needs, combining various elements like power, signal, and fluid transfer. Available in non-standard sizes, with multiple circuit options and protection levels up to IP65.
About Electrical Rotary Joints (Slip Rings)
A slip ring is an electrical connector designed to conduct current or data across a rotating interface, replacing the need for dangling wires that would inevitably twist and break.
Key components
- Rings
- Circular, conductive tracks (usually made of copper or a precious metal alloy) mounted on the rotor (the rotating part)
- Brushes
- Stationary, conductive contacts (often graphite, carbon fiber, or a precious metal alloy) that rest on the rings and transfer the electrical current or signal
- Housing/Stator
- The fixed enclosure that holds the brushes and provides the mounting points for the stationary side
Typical applications
- Packaging Machinery: Transmitting power and control signals to rotating sealing heads or label applicators
- Cranes & Winches: Providing power and control signals to the rotating drum or trolley
- Robotics & Automation: Enabling unlimited joint movement in multi-axis robots without damaging wiring
- Turrets & Indexing Tables: Supplying power and control for precision positioning systems
- Wind Turbines: Transmitting pitch-control signals and monitoring data from the rotating hub to the nacelle
- Medical Equipment (e.g., CT Scanners): Handling high-speed data transfer and power delivery during continuous rotation
