RS PRO Uninsulated Copper Ring Terminal 10 mm Stud Size 4 AWG Wire Size, Tin Plated Contact 841-7627

RS PRO 841-7627 uninsulated ring terminal is a premium heavy-duty copper crimp terminal designed for 10 mm stud connections and 4 AWG wire sizes. Its thick-walled copper construction enhances conductivity and physical durability, while the tin plating provides corrosion resistance and facilitates soldering. This uninsulated terminal is engineered for robust and reliable electrical connections in diverse industries including industrial machinery, automotive applications, power supplies, and communication equipment.

The terminal's closed barrel securely grips multi-stranded cables with a funnel-shaped internal barrel that simplifies wire insertion. Its natural finish and precise sizing - with an outer ring diameter of 9.1 mm, inner ring diameter of 6.7 mm, and thickness of 1.2 mm - make it suitable for heavy-duty applications where safe electrical contact is critical. Operating between -30°C and 120°C, this ring terminal withstands demanding environments while complying with RoHS and ANSI/ESD Electrostatic Control standards.

Applications commonly include industrial control systems, automotive wiring harnesses, power supply connections, and domestic appliances. Proper crimping tools such as ratchet or hydraulic crimp tools are recommended for secure installation to maintain electrical integrity and mechanical performance.

Overall length is 36.9 mm, suitable for standard cable fastening requirements. The uninsulated design reduces the risk of short circuits only when used in appropriate controlled environments that prevent accidental contact. This product is manufactured in China and offers a dependable solution for professionals requiring consistent high-quality ring terminals.
