SMB Fakra Plug, 50 Ohm, 4 GHz — Crimp Termination for RG-174 and RG-316
The 2FA1-NCSP-C01W1: It carries the Code C keying variant of the Fakra interface, which prevents cross-mating with other code positions in multi-connector automotive harnesses. Rated at 50 Ohm characteristic impedance with a maximum operating frequency of 4 GHz. The zinc die-cast body with nickel finish and PTFE dielectric support the environmental stability required for outdoor-vehicle service life.
Cable Groups and Termination — Crimp Both Contact and Shield
This plug accepts RG-174, RG-188A, LMR-100, and M17/119-RG174 cables. The 2FA1-NCSP-C01W1 is compatible with RG-316 as listed in the cable group. Mating cycles are rated at 100 — adequate for the number of connect-disconnect events in a vehicle assembly line and subsequent service life, but not intended for frequent field swapping. The gold-plated centre contact and nickel body finish resist corrosion through those cycles in automotive environments.
