RS PRO TL Uninsulated Ring Terminal 10.5 mm Stud Size 1 AWG Heavy Duty Copper Grey 125-1963

RS PRO model 125-1963 is a TL series uninsulated ring terminal designed for heavy duty crimp applications involving large conductors. The terminal features a robust, thick-walled tubular body made of highly conductive copper, finished with tin plating for superior durability and resistance to corrosion, friction, and solderability. This ring terminal is engineered for secure connections to studs or posts, commonly found on battery terminals and industrial electrical panels.

Supporting 1 AWG wire sizes (metric equivalent to 50 mm²), the funnel-shaped internal barrel ensures easy wire insertion, enabling consistent and reliable crimps. The terminal’s inner ring diameter measures 10.5 mm, providing compatibility with industry-standard stud sizes, while its overall length of 44.5 mm facilitates ease of installation in wiring assemblies.

As an uninsulated component, this ring terminal is intended for environments where insulation is not required and short-circuit risk is minimal. Its closed design improves mechanical robustness and electrical conductivity, making it highly suitable for demanding applications including industrial control systems, machinery wiring, automotive harness assemblies, and high-power communication equipment.

The copper contact material offers excellent electrical performance, while the tin plating enhances strength and extends service life in corrosive or elevated temperature conditions. Rated for operating in a wide temperature range from -40°C to 150°C, it is dependable under varied industrial environments.

Compliant with RoHS and ANSI/ESD S20.20:2021 electrostatic control standards, this ring terminal is produced with attention to safety and environmental requirements. Its grey color allows for easy identification among terminal types, and the 2.9 mm thickness further substantiates its heavy duty properties.

Applications extend across industrial machinery, automotive systems, communication infrastructure, power supply installations, and domestic appliances requiring robust wire termination to a stud. Users should select the appropriate terminal size based on wire gauge and stud dimensions for optimal performance and safety.
