AlumaLight Backshells

Amphenol PCD AlumaLight Backshells are available in EMI/RFI shielded strain relief and band locks, as well as other environmental options. Offering approximately 50% weight savings over standard metal backshells, these backshells are ideally suited for commercial aerospace applications or any application where weight savings are critical. Amphenol PCD AlumaLight Backshells have a high shear strength with no breakage of coupling nuts and superior EMI performance.
