It ships as a five-piece set: the jack body, centre contact, crimp ferrule, housing, and a locking clip, all under one order code. This is the Code A keyed variant of the FA1-NASJ series, meaning the housing colour and keying position are set for a specific Fakra cavity assignment in automotive or infotainment harnesses. The jack is rated to 6 GHz with a 0.3 dB insertion loss, putting it in the standard-performance RF interconnect class — fine for GPS, cellular, and WiFi signal paths up to that frequency.
The crimp dimensions on this jack are tooled for RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 coax. If you need a cable outside this group — say RG-58 — the ferrule and centre contact diameters won't match, and the impedance match through the crimp zone will shift. Stick to the listed cable types for a 50 Ohm launch through the assembly.
Mating and Mechanical Fit
The latch replaces the threaded coupling typical of SMA connectors, making it faster to engage in a harness assembly. The locking clip is included in the kit and secures the housing to the connector body after crimp assembly. The nickel-plated brass body and black/jet housing colour are standard for the Code A key position.
