Cembre 2163710 S6-M6/1 uninsulated brazed seam copper ring terminal for 4–6 mm² conductors with M6 stud connection.
£0.26
The Cembre 2163710, also identified as the S6-M6/1, is a premium uninsulated brazed seam copper ring terminal designed to provide secure, low-resistance electrical terminations for stranded copper conductors. Manufactured from high-purity electrolytic copper with a corrosion-resistant electrolytic tin-plated finish, it delivers excellent conductivity, mechanical strength and long-term reliability in industrial and commercial electrical installations.
Its closed ring design provides a secure mechanical connection when fastened to an M6 stud or screw, making it particularly suitable for applications exposed to vibration or requiring dependable long-term electrical performance. The brazed seam barrel and internal knurling enhance conductor retention and ensure a consistent, high-quality crimp.
Designed for 4–6 mm² copper conductors, the Cembre 2163710 is widely used in industrial control panels, machinery, switchgear, OEM equipment and electrical distribution systems where reliable conductor termination is essential.
Ring terminals provide one of the safest and most secure methods of terminating conductors onto threaded studs and terminal screws. Their closed-ring construction helps prevent accidental disconnection while maintaining excellent electrical contact in environments exposed to vibration and mechanical stress.
The Cembre S6-M6/1 is manufactured from annealed electrolytic copper with a brazed seam barrel and electrolytic tin plating to provide excellent conductivity, corrosion resistance and dependable long-term performance across demanding industrial environments.
