Product details

SMB Fakra Jack for RG-58 Cable — Kit Includes Everything

The FA1-NCSJ-C04-0: This is a complete assembly kit — the order code delivers 5 pieces: the connector body, one contact, one ferrule, one housing, and one locking clip, all in one Bulk package. The jack terminates to RG-58 and compatible cables (RG-58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, 9907) using a crimp-on shield termination and a crimp contact. The latch lock provides vibration-resistant retention without a threaded coupling ring, making it suitable for automotive infotainment, telematics, and antenna interconnect applications where the Fakra interface is specified.

What the 50 Ohm, 6 GHz Rating Means for Your RF Path

The 6 GHz maximum frequency covers the 5 GHz Wi-Fi bands and GNSS/GPS signals. The 0.3 dB insertion loss at frequency is a per-connector budget figure.

Cable Compatibility — RG-58 and Beyond

The FA1-NCSJ-C04-0 is designed for RG-58 and its electrical equivalents: RG-58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. All share a similar 0.195-inch diameter dielectric and braid shield construction. The crimp ferrule and center contact are sized for this cable group. If you are using a cable outside this list, the crimp dimensions may not produce a reliable termination — verify the cable OD and dielectric diameter against the ferrule and contact specifications.
