SMB/Fakra Jack for Automotive Antenna Harnesses
The Amphenol RF 3FA1-NMSJ-C01W0 is a Code M-keyed SMB/Fakra jack, designed as the female receptacle for snap-in coaxial connections in automotive antenna systems. It handles frequencies up to 3 GHz with a 50 Ohm impedance, covering GNSS, cellular, and ISM bands. The latch lock fastening provides vibration-resistant retention without a threaded coupling, matching the Fakra standard for vehicle-grade interconnect. The body is zinc die cast with a tin finish, and the housing colour is orange or pastel, typical of Fakra code-colour keying.
The listed cable groups — RG-174, RG-188, RG-188A, RG-316, LMR-100, and M17/119-RG174 — cover the common small-diameter coax types used in antenna feeds.
