Donau Elektronik 218-50 johdin 2 x 0,14 mm² punainen/musta 50 m

Low-voltage wiring projects often fail when the conductor is too stiff or the insulation cracks under repeated bending. The Donau Elektronik 218-50 stranded wire solves this with a flexible 2-core design, each core composed of 18 fine copper strands with a total cross-section of 0.14 mm². Supplied on a 50-metre spool, it provides ample length for speaker connections, model building, switching circuits, and other low-current applications up to 1 A.

Who is it for

This cable suits hobbyists, electricians, and technicians who need a reliable, easy-to-route wire for low-voltage signal and control tasks. The red and black PVC insulation allows quick polarity identification, while the flat twin configuration keeps the pair neatly together during installation.

Main features

• 2 cores, each 0.14 mm², made of 18 copper strands (0.10 mm diameter) for high flexibility
• Red and black PVC insulation for clear polarity marking and mechanical protection
• Flat twin construction (approx. 2.2 x 4.4 mm) for easy routing in tight spaces
• 50-metre spool for multiple projects or continuous runs
• Rated for 50 V nominal voltage and up to 1 A current
• Operating temperature range from -20 °C to +70 °C
• RoHS compliant

Tips

For best results, strip the insulation carefully to avoid nicking the fine strands. When soldering, pre-tin the stranded ends to ensure a solid connection. The flat twin design is ideal for running along surfaces or through conduits where a round cable might twist.
