Cembre 2145742 RKY-U6 reinforced pre-insulated fork terminal for 0.25–1.5 mm² conductors with 6.4 mm fork opening and anti-vibration construction.
£0.23
The Cembre 2145742 (RKY-U6) 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-U6 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 vibration resistance. 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 6.4 mm (M6) fork opening, the Cembre 2145742 allows fast removal and replacement without completely removing the fixing screw, making it ideal for maintenance and service applications.
Fork terminals provide secure electrical connections while allowing faster maintenance than ring terminals because they can be removed without completely removing the fixing screw. The reinforced copper sleeve used in the Cembre RKY series improves cable retention and provides excellent resistance to vibration in demanding industrial environments.
Cembre reinforced terminals are widely used by industrial electricians, machine builders and panel manufacturers where reliable electrical connections and efficient servicing are required.

It provides secure crimped fork terminations for flexible copper conductors connected to M6 screw terminals.
The RKY-U6 is designed for flexible copper conductors from 0.25 mm² to 1.5 mm².
Fork terminals allow quicker maintenance because the conductor can be removed without completely removing the fixing screw.
It is manufactured from electrolytic tin-plated copper with durable halogen-free PA6.6 insulation.
The terminal is crimped onto the conductor using an appropriate crimping tool before being secured beneath an M6 screw terminal.
Cembre electrical connection products are trusted by panel builders, OEM manufacturers and industrial electricians for delivering safe, reliable and professional electrical terminations across demanding industrial environments.
