Fakra SMB Housing — 3FA1-NZSJ-C01E0
The Amphenol RF 3FA1-NZSJ-C01E0 is a Fakra SMB housing — a color-coded, keyed shell that accepts SMB and Fakra female contacts. It is the housing half of a Fakra interconnect, not a complete connector; contacts are ordered separately. The Blue, Water color and Code Z keying identify the application-specific variant, preventing mis-mating in multi-connector harnesses. The housing is molded from a Polyphenylene Ether (PPE) and Polystyrene (PS) blend, giving it the mechanical stiffness and thermal stability needed for automotive-grade coaxial connections.
Compatible Contacts and Mating
This housing is designed for use with SMB and Fakra female contacts. The Code Z keying and Blue color ensure that only the matching Fakra plug with the same code will mate — a deliberate cross-mate prevention feature common in automotive RF harnesses where multiple coax lines (GPS, satellite radio, cellular) share a connector cluster.
