Why Choose the Cembre 2163590 Non-Insulated Copper Ring Terminal?
The Cembre 2163590, also identified as S2.5-M6, is a premium non-insulated copper ring terminal designed to provide secure, low-resistance electrical terminations for stranded copper conductors. Manufactured from high-purity electrolytic copper with an electrolytically tin-plated finish, it delivers excellent electrical conductivity, corrosion resistance and dependable long-term performance in demanding industrial and commercial installations.
Designed for professional electricians, panel builders and OEM machine manufacturers, the terminal incorporates a brazed seam barrel for exceptional mechanical strength together with an internally rifled barrel that improves conductor grip and electrical contact after crimping. The closed ring design provides a secure, vibration-resistant fixing for permanent electrical connections.
Suitable for 1.5–2.5 mm² (16–14 AWG) conductors and an M6 (1/4") stud, the Cembre 2163590 is ideal for industrial control panels, switchgear, machinery, automation systems and power distribution equipment where dependable cable terminations are essential.
