What This Fakra Plug Does in the Assembly
The 2FA1-NKRP-PCB-6: The locking ramp provides audible positive retention — standard for Fakra connectors used in infotainment, telematics, and antenna feeds where vibration can unseat a push-on interface.
Why 4 GHz Matters for Your Signal Path
Rated to 4 GHz maximum frequency, this plug covers GPS, cellular (LTE/5G sub-6 GHz), and DAB/SiriusXM bands but falls short of the 6 GHz ceiling on the FA1-NCRP-PCB-8 (Code C) sibling. If your design needs headroom above 4 GHz — for dual-band Wi-Fi or emerging 5G NR bands — step up to the Code C variant. At 4 GHz and below, the 50 Ohm impedance and gold-plated brass center contact keep insertion loss and VSWR within the Fakra interface spec.
Temperature Range and Build Materials
The gold-over-brass center contact resists corrosion through 100 mating cycles — adequate for a single harness mate but not for repeated field-service disconnect. The curry-colored housing identifies the Code K keying, preventing mis-mating with other Fakra codes on the same harness.
