£0.54
The Cembre 2145878 BKY-M12 is a premium blue reinforced insulated ring terminal engineered to provide secure, vibration-resistant electrical connections for demanding industrial and commercial applications. Manufactured by Cembre, this terminal is designed for 1.5–2.5 mm² copper conductors and features an M12 (13 mm) stud connection, making it ideal for electrical control panels, switchgear, machinery, OEM equipment and industrial automation systems.
Part of the renowned Cembre BKY reinforced terminal series, the BKY-M12 incorporates a copper reinforcing sleeve positioned between the barrel and insulation. During crimping, the sleeve deforms around the cable insulation, creating exceptional mechanical strength, improved conductor retention and outstanding resistance to continuous vibration and oscillation.
Manufactured from high-purity electrolytic copper with a corrosion-resistant tin-plated finish and durable halogen-free Polyamide PA6.6 insulation, the Cembre 2145878 delivers dependable long-term electrical performance in professional industrial installations.
The BKY reinforced terminal range has been specifically developed for electrical installations exposed to continuous vibration, oscillation and mechanical stress. The integrated copper reinforcing sleeve improves crimp integrity while maintaining excellent electrical conductivity throughout the service life of the installation.
Ideal for industrial machinery, electrical control panels, switchgear and power distribution systems, the Cembre BKY-M12 provides dependable electrical connections where long-term reliability is essential.
