The wire end ferrule 167H from Klauke is a marking element specifically designed for fine and very fine wire conductors, particularly intended for conductor cross-sections according to DIN EN 60228 class 5 and 6. With an insulating length of 6 mm and a total length of 10.0 mm, it provides precise coverage for cable ends, while the insulated version ensures safe electrical isolation. The ferrule is coloured light blue, corresponding to colour code 1, and can thus be used in electrical installations for unambiguous conductor identification according to standards. The construction with Easy-Entry insulation allows for splice-free cable entry, reducing installation time and minimising the risk of incorrect connections.

Wire end ferrule
The wire end ferrule 167H is made of tinned copper (Cu), ensuring good electrical conductivity and corrosion resistance. The insulation is halogen-free, which is advantageous for use in enclosed spaces or installations with high safety requirements. The temperature resistance up to 105 °C makes the ferrule suitable for applications in environments with increased thermal load, such as industrial controls or electrical installations with high loads. The ferrule is CSA-listed, confirming compliance with the safety requirements of the Canadian Standards Association.

Applications
The wire end ferrule 167H is primarily used in electrical installations, automation technology, and industrial electronics, where safe and unambiguous identification of fine conductors is required. It is particularly suitable for applications requiring high precision in connecting cables and connectors. The colour coding according to colour code 1 supports unambiguous assignment of conductors in complex circuits, reducing error rates during commissioning and maintenance.

Functions and equipment in detail
The Easy-Entry insulation enables quick and secure cable insertion into the ferrule without additional tools or splicing. The insulation is dimensioned to fully enclose the conductor, ensuring electrical insulation. The ferrule is designed for a conductor cross-section of 0.25 mm², making it suitable for very fine wires, such as those found in control lines or sensor cables. The total length of 10.0 mm ensures sufficient coverage of the cable end to guarantee a secure connection.

Technology explained simply
The wire end ferrule 167H consists of a metallic core made of tinned copper, ensuring reliable electrical contact, and a surrounding insulating layer made of halogen-free plastic material. The insulation is designed to fully enclose the conductor, ensuring electrical separation from other conductors or metal parts. The light blue colour corresponds to colour code 1, used in electrical installations to identify specific conductors. The temperature resistance up to 105 °C allows use in environments with increased thermal load without the insulation losing its function.

Compatibility and accessories
The wire end ferrule 167H is compatible with fine and very fine conductors according to DIN EN 60228 class 5 and 6. Suitable accessories include wire end ferrules in DIN 46228 part 4 format, 0.25 mm², 6 mm insulated, in light blue. These are also designed for use with fine conductors and support uniform identification in electrical installations. Using accessories from the same system ensures consistent colour and shape design, improving clarity in complex installations.

Installation and mounting
The installation of the wire end ferrule 167H is done by simply inserting the cable into the ferrule, with the Easy-Entry insulation enabling smooth and quick connection. No additional tools are required, and the cable is inserted without splicing. The ferrule is designed to securely hold the conductor and ensure a stable electrical connection. Installation typically takes place directly at the cable end before it is inserted into a connector or terminal.

Operational advantages
The wire end ferrule 167H offers high reliability in operation through stable electrical connection and secure insulation. The halogen-free insulation reduces fire hazard and the formation of toxic fumes in case of fire. The colour coding according to colour code 1 supports unambiguous conductor identification, simplifying maintenance and servicing. The CSA listing confirms safety compliance and enables use in installations subject to corresponding safety standards.
