27mm Outer Diameter 37 Circuits Solid Shaft Slip Ring Low Noise Rotary Electrical Connector For Automation Robotic Packaging Equipment

Our 27mm OD 37 circuits solid shaft conductive slip ring is a compact rotary electrical connector developed for rotating equipment without hollow through-hole requirements. Its integrated solid shaft structure greatly simplifies assembly layout and enhances overall structural rigidity, while the 27mm slim outer diameter perfectly fits equipment with limited installation space, delivering multi-channel signal and power transmission capacity with 37 independent circuits at the same time.

The internal contact system adopts high-purity precious metal alloy, which effectively reduces contact resistance fluctuation and mechanical abrasion during long-cycle rotation. It eliminates signal distortion and crosstalk between circuits, enabling synchronous stable transmission of weak control signals and rated power current. The outer shell is made of hard anodized aluminum, with outstanding anti-corrosion and anti-scratch performance; standard IP54 dust and splash resistance meets general industrial workshop working conditions, and IP65 waterproof upgrade is available for humid or dusty harsh environments.

This solid shaft slip ring supports continuous working speed up to 300 RPM, with a service life exceeding 10 million rotations. The sealed internal structure requires no regular lubrication or maintenance, significantly lowering your equipment’s post-operation maintenance cost. Each circuit is separated by insulating partitions to guarantee excellent insulation resistance and breakdown voltage performance, avoiding short-circuit risks during long-time running.

Widely used in multiple industrial fields, it serves as the core rotary component for multi-joint robotic arms, automated packaging machinery, surveillance monitoring PTZ cameras, textile winding equipment and small rotary testing platforms. We provide flexible personalized customization: adjustable single-circuit rated current, extended wiring harness length, special wire connectors and upgraded protective structures. All finished slip rings undergo strict electrical continuity, insulation and aging rotation tests before shipment, to ensure consistent, reliable long-term operation of your automated rotary equipment.
