Composite Backshells

Amphenol PCD Composite Backshells are available in a straight unfinished backshell, a 90° unfinished backshell, and an unfinished split-shield ring backshell. Amphenol PCD Composite Backshells are ideal for anywhere lightweight connector support is needed. These backshells are especially suitable for commercial aerospace applications, including cockpits, cabins, wireframes, and avionics.
