This connector sits in the FA1 series, the Fakra-latched variant of the SMB family, built for automotive-grade RF interconnects where vibration resistance and a positive lock are required. ## Cable Prep and Field Termination The kit includes five pieces per connector: the jack body, the centre contact, the ferrule, the housing, and the locking clip. Cable compatibility covers RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907 — all 50 Ohm cables with a similar dielectric diameter. The latch lock snaps onto the mating Fakra plug and holds under vibration; the blue signal housing colour codes the connector for Code C keying, which prevents cross-mating with other Fakra codes. ## What the 6 GHz and 100-Cycle Ratings Mean for the Job The 6 GHz ceiling covers GNSS and WiFi 6/6E bands with margin. The 0.3 dB insertion loss is the total through the mated pair — budget it against your system link loss before the LNA.","metaTitle":"Amphenol RF FA1-NCSJ-C04-6 SMB Fakra Jack, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF FA1-NCSJ-C04-6 SMB Fakra jack, female socket, 50 Ohm, 6 GHz max, crimp termination for RG-58 cable.
