Klauke 4R12MS Tubular Cable Lug 25mm² M12 E-Cu Galvanically Tinned with Inspection Hole

The Klauke 4R12MS is a high-quality tubular cable lug designed for reliable electrical connections in power distribution, control cabinets, and industrial applications. Manufactured from electrolytic copper (E-Cu) with an electro-tinned surface, it offers excellent corrosion resistance and long-term conductivity. The integrated inspection hole allows for visual verification of proper conductor insertion before crimping, ensuring secure and consistent connections.

Advantages

Electro-tinned surface provides superior corrosion protection and maintains low contact resistance. The inspection hole enables quick visual confirmation of correct conductor placement, reducing installation errors. Complies with DIN 46235 standard for crimp connections, ensuring compatibility with standard crimping tools and dies.
