£0.20
The Cembre 2145856 BKY-M5 is a premium blue reinforced insulated ring terminal engineered to provide secure, vibration-resistant electrical connections in demanding industrial and commercial environments. Manufactured by Cembre, this terminal is designed for 1.5–2.5 mm² copper conductors and features an M5 (5.3 mm) stud connection, making it ideal for control panels, switchgear, industrial machinery, OEM equipment and automation systems.
Part of Cembre's renowned KY reinforced terminal series, the BKY-M5 incorporates a copper reinforcing sleeve between the barrel and insulation. During crimping, this sleeve deforms around the cable insulation, producing exceptional mechanical strength, superior vibration resistance and outstanding long-term electrical reliability.
Manufactured from high-purity electrolytic copper with a corrosion-resistant tin-plated finish and durable halogen-free Polyamide PA6.6 insulation, the Cembre 2145856 is the ideal solution where dependable electrical terminations are essential in harsh industrial environments.
The BKY reinforced series is specifically developed for electrical installations subjected to continuous vibration, oscillation and mechanical stress. Its reinforced copper sleeve significantly improves conductor retention while maintaining excellent electrical conductivity throughout the service life of the installation.
Suitable for industrial machinery, electrical control panels, switchgear and automation equipment, the Cembre BKY-M5 provides dependable electrical connections where reliability and durability are critical.
