Right-angle Fakra plug, Code B, rated to 4 GHz
The Amphenol RF 2FA1-NBRP-PCB-6 is a Code B SMB/Fakra plug with a single male pin, designed for right-angle through-hole PCB mounting. It carries the 50 Ohm impedance standard for automotive RF interconnects and is rated to 4 GHz maximum frequency. The locking ramp fastening type gives it a positive mechanical latch beyond what a standard snap-on SMB provides — meaning it won't vibrate loose in a vehicle harness. A 100-cycle mating life, gold-plated brass center contact, and PTFE dielectric round out the signal path. The tin-plated zinc die-cast body and cream housing color identify this as the Code B keying variant in the 2FA1 series.
Termination and mounting checklist
The shield termination is solder — no crimp ferrule or board-lock retention beyond the through-hole joints.
