Why Choose the Cembre 2145853 BKY-M4 Reinforced Ring Terminal?
The Cembre 2145853 BKY-M4 is a premium blue reinforced insulated ring terminal designed to provide secure, vibration-resistant electrical connections in demanding industrial and commercial environments. Manufactured by Cembre, this terminal accommodates 1.5–2.5 mm² copper conductors and features an M4 (4.3 mm) stud connection, making it ideal for electrical control panels, switchgear, industrial machinery and OEM automation equipment.
Manufactured from high-purity electrolytic copper with a corrosion-resistant electrolytic tin-plated finish, the BKY-M4 incorporates Cembre's reinforced anti-vibration technology. A copper reinforcing sleeve positioned between the barrel and insulation deforms during crimping to produce exceptional mechanical strength, improved conductor retention and long-term electrical reliability.
The halogen-free Polyamide PA6.6 insulation features a funnel-shaped entry that simplifies conductor insertion while preventing strand damage during installation. Designed for continuous vibration and mechanical stress, the Cembre 2145853 delivers dependable long-term performance for professional electrical installations.
