The solid contacts are designed for use with larger wire size and heavy duty applications. Solid contacts are manufactured using a cold heading process with solid copper alloy wire and are available with either a nickel or gold plating finish. These contacts terminate wire from 6 AWG to 20 AWG (13 – 0.5mm2) and are available in 5 sizes each of the pin and socket. DEUTSCH industrial environmentally sealed electrical connectors are for critical applications and are designed to withstand the harshest and most challenging environments.
