Why Choose the Cembre 2145847 BKY-M3.5/1 Reinforced Ring Terminal?

The Cembre 2145847 BKY-M3.5/1 is a premium blue reinforced insulated ring terminal designed to provide secure, vibration-resistant electrical connections in demanding industrial and commercial applications. Manufactured by Cembre, this terminal is suitable for 1.5–2.5 mm² copper conductors and features an M3.5 stud connection, making it ideal for control panels, switchgear, machinery and OEM automation equipment.

Manufactured from high-purity electrolytic copper with a corrosion-resistant tin-plated finish, the BKY-M3.5/1 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 helping prevent strand damage during installation. This makes the Cembre 2145847 an ideal choice for professional electricians, panel builders and maintenance engineers requiring dependable electrical terminations.
