Neotech's NCB-80 banana plugs are made from high-purity OFC copper and are gold-plated for optimum resistance to corrosion and oxidation. A cryogenic treatment has also been applied to the contacts to improve their conductivity and durability. NCB-80 banana plugs accept cables up to Ø5mm in diameter. The cables are easily and efficiently fitted using a locking screw. The overall dimensions of these banana plugs are 55mm long and 15mm thick. These Neotech NCB-80 banana plugs have a very good design quality and are therefore ideal for creating high-performance HiFi speaker cables.
