Product details

RF Connector for RG-58 and LMR-195 Cable Assemblies

The Amphenol RF FA1-NBSJ-C04-6 is a Code B keyed SMB / Fakra jack (female socket) rated for 50 Ohm systems from DC to 6 GHz. The 0.3 dB insertion loss across the band keeps the link budget tight for automotive-grade Fakra applications like GPS, satellite radio, or cellular antenna feeds.

Cable Prep and Termination Checklist

Crimp termination for both shield and center contact — the shield is crimped over the ferrule, the center contact is crimped to the stripped conductor. The free-hanging (in-line) mount and latch-lock fastening mean the mated pair stays engaged without a secondary nut, but the 100-cycle mating life is a reminder that this is a field-serviceable connector, not a permanent solder joint. The Code B keying prevents cross-mating with other Fakra color codes in multi-antenna harnesses.
