Cembre 2146023 GKY-U4 reinforced insulated yellow fork terminal for 4-6 mm² conductors with M4 fork connection, manufactured from tin-plated electrolytic copper with halogen-free PA6.6 insulation.
£0.36
The Cembre 2146023 GKY-U4 is a premium yellow reinforced insulated fork (spade) terminal engineered to provide secure, vibration-resistant electrical terminations for industrial control panels, switchgear, machinery and OEM equipment. Manufactured by Cembre, this professional-grade fork terminal is specifically designed for demanding applications where dependable electrical performance and long-term mechanical reliability are essential.
Manufactured from 99.95% pure electrolytic copper with a durable electrolytic tin-plated finish, the GKY-U4 offers outstanding conductivity, corrosion resistance and long service life. Its reinforced anti-vibration copper sleeve becomes part of the crimp during installation, creating an exceptionally secure electrical and mechanical connection, even in applications exposed to continuous vibration and movement.
Designed for 4–6 mm² conductors and featuring a 4.3 mm fork opening (M4 stud), the Cembre 2146023 enables rapid installation and removal without fully removing the fixing screw, reducing maintenance time while ensuring dependable electrical performance.
Reinforced insulated fork terminals provide dependable low-resistance electrical connections while significantly improving resistance to vibration and continuous mechanical stress. Their fork design allows conductors to be installed or removed without fully removing the terminal fixing screw, reducing servicing time and simplifying maintenance.
The Cembre KY reinforced terminal range has been developed specifically for harsh industrial environments where electrical integrity and mechanical durability are essential. The anti-vibration copper sleeve improves crimp strength while the halogen-free insulation delivers reliable long-term performance.
