SMB Fakra Plug for 4 GHz RF Harnesses
The FA1-NZSP-PCB-2: This connector operates up to 4 GHz, making it suitable for automotive antenna feeds, telematics modules, and industrial wireless links where the Fakra interface is specified. The locking ramp fastening provides a positive mechanical retention that standard push-on SMB connectors lack — the ramp engages with the mating receptacle and holds against vibration until deliberately released.
Code Z Keying and Harness Fit
This FA1-NZSP-PCB-2 carries the Code Z keying variant, which is a Fakra colour-and-mechanical coding that prevents cross-mating with other Fakra codes in the same harness. Code Z uses a blue housing with a specific key geometry; the mating receptacle must also be Code Z. The locking ramp is integral to the Fakra standard — it provides the audible and tactile click that confirms full engagement, and the ramp profile is consistent across all Fakra codes. For a harness builder, the keying means this plug only mates with the matching Code Z jack, so the BOM must pair the correct code on both halves.
