Why are wire end ferrules a standard in professional control cabinets? When you tighten a screw terminal directly onto stranded wire, the individual copper strands can splay out, leading to a weak connection, increased resistance, and even short circuits. The QUADRIOS 22C426 prevents this by bundling all the strands of a 0.75 mm² cable into a solid, robust pin.

This ferrule consists of a tin-plated copper barrel that is precisely crimped onto the stripped wire. The attached gray polyamide collar provides a safe grip and prevents the ferrule from being inserted too far into the terminal. Its color serves as an immediate gauge identifier, following the DIN 46228-4 standard. The result is a clean, secure, and repeatable termination that maximizes contact area and withstands vibration.

Ideal for use in PLC systems, relay outputs, and any screw-type terminal block. The 8 mm pin length is a universal standard. For a perfect crimp, always pair this ferrule with a ratcheting crimping tool that has a die specifically designed for 0.75 mm² ferrules.
