Why Choose the Cembre 2161970 Ring Terminal?
The Cembre 2161970 is a premium non-insulated copper ring terminal designed to provide secure, permanent electrical terminations for copper conductors in industrial and commercial applications. Manufactured by Cembre, this high-quality terminal combines electrolytic copper construction with precision engineering to deliver excellent conductivity, outstanding mechanical strength and long-term reliability.
Designed for 1.5–2.5 mm² (16–14 AWG) conductors, the terminal features an M5 stud connection and is supplied as the S2.5-M5 variant. The brazed seam barrel and internal knurling improve conductor retention while the electrolytic tin-plated finish provides excellent corrosion resistance in demanding industrial environments.
Suitable for professional compression crimping, the Cembre 2161970 is widely used by panel builders, OEM manufacturers and maintenance engineers for electrical control panels, machinery, switchgear and automation systems requiring dependable bolted electrical connections.
