The connector includes four pieces in the package: the connector body, a crimp contact, a ferrule, and a shroud — everything needed to terminate one cable end. The Fakra II interface adds a latch-lock fastening system, which gives a positive mechanical retention beyond what a standard SMB snap-on provides, making it suited for automotive and industrial environments where vibration can unseat a plain push-on connector. The 6 GHz frequency ceiling covers common automotive RF bands (GPS, cellular, Wi-Fi) but not mmWave; above 6 GHz the VSWR rises beyond what the SMB interface geometry can hold flat. The 335 V voltage rating is generous for signal-level coax but matters if the line carries DC bias for an active antenna or LNA power feed. The 50 mating cycle rating is low — this is a set-and-forget connector for a harness assembly, not a test-port or frequent-disconnect point. The contact and shield terminate by crimp — the centre contact crimps onto the RG-316 centre conductor, and the ferrule crimps over the braid and jacket. The shroud (blue/water colour) provides environmental sealing at the mating face when paired with the corresponding Fakra II receptacle.","metaTitle":"Molex 0734036270 SMB Fakra II Plug, 50 Ohm, RG-316, 6 GHz","metaDescription":"Molex 0734036270 SMB Fakra II plug, female socket, 50 Ohm impedance, for RG-316 cable, 6 GHz max, 335 V, -40°C to 105°C.
