Why Choose the Cembre 2145739 RKY-U5 Fork Terminal?
The Cembre 2145739 (RKY-U5) is a premium-quality pre-insulated anti-vibration fork terminal designed to provide secure, reliable electrical terminations for flexible copper conductors. Manufactured by Cembre, it is engineered for industrial control panels, machinery, automation systems and OEM electrical equipment where dependable electrical performance and rapid installation are essential.
Manufactured from 99.95% pure electrolytic copper with a durable minimum 3 μm tin-plated finish, the RKY-U5 features Cembre's reinforced copper sleeve between the conductor barrel and insulated collar. During crimping, this reinforcement grips the cable insulation to improve mechanical retention while maintaining excellent conductivity and long-term resistance to vibration. The halogen-free PA6.6 polyamide insulation incorporates a funnel-shaped entry that simplifies conductor insertion and improves installation efficiency.
Designed for 0.25–1.5 mm² flexible copper conductors with a 5.3 mm (M5) fork opening, the Cembre 2145739 allows fast removal and replacement without completely removing the fixing screw, making it ideal for maintenance and service applications.
