RJ45 Connectors (50µ vs. 30µ)

Most people don't realize there are differences in the end connectors called RJ-45 8p8c plugs. They may all appear to look a like but the difference lies in which materials make up the contacts. Some are made with Copper while others are plated with Gold. As you may have guessed Gold is the best contact material used... but here is the catch! There are different concentrations of Gold plugs. Some are 30µ (30 micro inches) of Gold while the best are 50µ (50 micro inches) of Gold. 50µ is almost 20 Times as thick as 30µ plugs!
