£0.29
The Cembre 2145842 BKY-M3 is a premium blue reinforced insulated ring terminal designed to provide secure, vibration-resistant electrical connections for professional industrial and commercial wiring applications. Manufactured by Cembre, this terminal is suitable for 1.5–2.5 mm² copper conductors and features an M3 (3.2 mm) stud connection, making it ideal for control panels, switchgear, machinery and industrial automation equipment.
Manufactured from annealed high-purity electrolytic copper with a corrosion-resistant electrolytic tin-plated finish, the BKY-M3 incorporates Cembre's reinforced anti-vibration design. A funnel-shaped copper reinforcing sleeve positioned between the barrel and insulation deforms during crimping to provide exceptional mechanical strength, improved conductor retention and outstanding electrical performance.
The halogen-free Polyamide PA6.6 insulation features a funnel-shaped entry that simplifies conductor insertion while preventing strand damage during installation. This makes the Cembre 2145842 an excellent choice for panel builders, electrical contractors and OEM manufacturers requiring dependable long-term performance.
The BKY reinforced series has been specifically developed for applications exposed to continuous vibration, oscillation and mechanical stress. The reinforced copper sleeve provides improved crimp integrity while maintaining excellent electrical conductivity throughout the life of the installation.
Suitable for industrial control panels, switchgear, machinery and OEM equipment, the Cembre BKY-M3 delivers dependable electrical connections where reliability is critical.
