The **ID20mm** through-bore slip ring is a robust rotary joint designed for industrial applications requiring reliable power transmission through a rotating assembly. Featuring a generous **20mm (0.78 inch) hollow center**, it allows for the passage of mechanical shafts, pneumatic lines, or complex cable bundles. This model is equipped with **2 high-power channels**, each rated for a continuous **10A** at voltages up to **600VAC/DC**. Engineered with premium **Gold Alloy** contacts, it ensures exceptionally low electrical noise and stable conductivity even at speeds up to **500 rpm**. Its versatile design supports both vertical and horizontal mounting, making it an ideal choice for heavy-duty robotics, packaging machinery, and rotary tables.
