£0.27
The Cembre 2145705 (RKY-M8) is a premium-quality pre-insulated anti-vibration ring terminal designed to provide secure, long-lasting electrical terminations for flexible copper conductors. Manufactured by Cembre, it is engineered for industrial control panels, machinery, OEM equipment and automation systems where dependable electrical performance and superior resistance to vibration are essential.
Manufactured from 99.95% pure electrolytic copper with a minimum 3 μm tin-plated finish, the RKY-M8 incorporates Cembre's reinforced copper sleeve between the conductor barrel and the insulated collar. During crimping, this reinforcement grips the cable insulation, improving mechanical retention while maintaining outstanding electrical conductivity and long-term reliability.
Designed for 0.25–1.5 mm² flexible copper conductors with an M8 stud fixing, the Cembre 2145705 is an ideal choice for panel builders, maintenance engineers and industrial electricians requiring professional-quality, vibration-resistant cable terminations.
Ring terminals provide permanent, vibration-resistant electrical connections that remain securely fastened under demanding operating conditions. The reinforced copper sleeve integrated into the Cembre RKY design improves cable retention while maintaining excellent electrical performance throughout the service life of the installation.
The Cembre RKY series is trusted worldwide by industrial electricians, OEM manufacturers and panel builders for dependable electrical terminations in machinery, automation systems and industrial control equipment exposed to continuous vibration.
