SMB Fakra Jack for RG-174/316 Coax — Code A Keyed
The Amphenol RF FA1-NARJ-C01-0 is a right-angle SMB Fakra jack, female socket, terminated for RG-174, 188, 188A, 316, and LMR-100 cable groups. It carries the Code A keying variant — the color-coding and mechanical polarization that prevents cross-mating with other Fakra codes in a multi-connector harness.
Cable Prep and Termination — Crimp Shield, Solder Center
Shield termination is crimp; the center contact is solder. That means you strip the coax, crimp the ferrule over the braid, then solder the center conductor into the beryllium copper pin. The PTFE dielectric body handles the -40°C to 100°C operating range without creeping — important for an under-hood or exterior antenna lead.
Mating Cycles and Retention
The right-angle exit keeps the cable routed flat against the panel or module face.
