QPL Composite Plated EMI/RFI Braided Backshells

Amphenol PCD QPL Composite Plated EMI/RFI Braided Backshells offer effective shielding due to the 360° contact of the braid and are suitable for weight-sensitive applications. Composite backshells are sought after for harsh environments because metal backshells are susceptible to corrosion. These backshells feature a pre-shielded strain relief, EMI/RFI shielding, and AS85049 qualification. Amphenol PCD QPL Composite Plated EMI/RFI Braided Backshells mate with MIL-DTL-38999 Series III connectors and are ideal for avionics, communications, military aerospace, and naval applications.
