The 031-321-1012 is a BNC crimp plug connector designed for RG59 double-braided coaxial cable applications. It features a 50 ohm impedance interface with brass body and contact materials finished in nickel and gold plating respectively, and a PTFE natural insulator for reliable signal transmission. The connector operates across a wide temperature range of -65°C to +165°C, ensuring stable performance in demanding environments. It is compatible with Belden 8281, 8281B, and 8281F cables and is crimped using Amphenol-specified tools and die sets for secure cable termination. This connector is commonly used in RF and video applications where impedance matching and signal integrity are critical.
