Our Cat5e cables feature a 50 micron gold plated RJ45 head. You can select a variety of colors -- Blue, Black, and White. All our iMBAPrice cables come with a lifetime warranty! What does 50 micron Gold plated mean? On each end of this iMBAPrice Cat5e Ethernet patch cable contains a gold plated tip to maintain optimum conductivity. Since gold is a well known high conductive and non-corrosive metal, thicker gold plating means greater protection from corrosion, making your product last longer. Unlike the usual lowest grade gold plating thickness (3-6 micron) commonly found it other gold plated Cat5e cables, this gold plated RJ45 plug contains the highest grade of gold plated thickness available in the market -- 50 micron. Whether you install your cables high humidity environment, or a non clean air environment
