Why Choose the Cembre S6-U3.5 Fork Terminal (2164170)?
The Cembre 2164170 (S6-U3.5) is a premium non-insulated copper compression fork terminal designed to provide secure, low-resistance electrical connections while allowing fast installation and removal without completely removing the fixing screw. Manufactured from high-purity electrolytic copper with an electrolytic tin-plated finish, it delivers excellent electrical conductivity, corrosion resistance and dependable long-term performance.
Designed for professional electricians, panel builders and OEM machine manufacturers, the S6-U3.5 features a brazed seam barrel with internal rifling to maximise conductor retention and ensure consistent crimp quality. Suitable for 4–6 mm² copper conductors, it accommodates a No. 6 (3.5 mm) fixing stud, making it ideal where equipment requires frequent maintenance or replacement.
Its robust construction makes it ideal for electrical control panels, industrial machinery, switchgear, motor control centres and automation equipment where reliable cable terminations are essential.
