Black-Zinc Nickel-Finish Backshell Clamps

Amphenol PCD Black-Zinc Nickel-Finish Backshell Clamps are RoHS-compliant replacements for cadmium plating. These clamps offer a cost-effective cable holding option over cadmium and provide environmental protection. The series is available in a variety of shell sizes (11 through 48), both military (MIL) specification and commercial types, and with EMI/RFI shielding. The clamps clean up the cable after termination and provide good strain relief at the termination area. Amphenol PCD Black-Zinc Nickel-Finish Backshell Clamps are suitable for aeronautical and military applications.
