RJ11 and RJ45 Modular Plugs

Solid vs Stranded: Solid wire consists of one piece of metal wire. Stranded wire is composed of a bundle of thinner wires. Choose the same type of plug as the wire you are using.

6, 30, and 50 micron: Thickness of gold plating on contacts. The thicker, the better protection against corrosion and aging. 50 micron has the best protection. While 6 micron is fine for office environment, we recommend 30 or 50 micron for dusty or chemical environments. Our patch cables are using 50 micron highest grade.
