QPL Composite Plated Bandlock Backshells

Amphenol PCD QPL Composite Plated Bandlock Backshells are suitable for weight-sensitive applications and offer plated and unplated options. Due to the composite construction of these backshells, they perform better in harsh environments, whereas metal backshells are susceptible to corrosion. These backshells provide superior strain relief, are qualified to AS85049 standards, and mate with MIL-DTL-38999 Series III connectors. Amphenol PCD QPL Composite Plated Bandlock Backshells are ideal for applications where work is done frequently, such as commercial and military aerospace, communications, shipboards, and space applications.
