It is a female socket with a 50 Ohm impedance, rated to 3 GHz, and mates with the corresponding Code H Fakra plug via a latch lock. The connector is IP67-rated when mated. It terminates to RG-174, RG-188, or RG-316 coaxial cable groups — the center contact is soldered, and the shield is crimped. ## 50 Ohm, 3 GHz, IP67 — What the Ratings Mean The 3 GHz maximum frequency covers GPS, cellular (up to 2.7 GHz), and ISM bands — for higher-frequency applications like 6 GHz Wi-Fi, a Fakra variant with a higher ceiling would be needed. The IP67 seal means the mated connector is dust-tight and can survive immersion in 1 meter of water for 30 minutes, which is the typical requirement for roof-mounted antennas or underbody harnesses. The 100 mating cycles are moderate — enough for production test and field service, but not for frequent disconnect-reconnect in a lab fixture. ## Code H Keying and Cable Termination Code H is one of the Fakra color/slot keying variants — the violet/heather housing ensures it only mates with a Code H plug, preventing cross-mating with other Fakra codes (A through Z) in a multi-connector system. The connector is free-hanging (in-line) with a right-angle cable exit option, which helps route coax in tight spaces behind a dashboard or inside a head unit. Termination is a two-step process: solder the center conductor to the gold-plated beryllium copper contact, then crimp the shield braid to the tin-plated zinc body. The PTFE dielectric maintains consistent impedance through the termination zone. ## Cross-Shop: FA1-NZSJ-C01-0 The FA1-NZSJ-C01-0 is a close functional peer in the same Fakra family, but with Code Z keying (blue/water housing) and crimp contact termination instead of solder. It also supports a broader cable group that includes LMR-100 and M17/119-RG174. If your build uses crimp center contacts or needs Code Z keying, the FA1-NZSJ-C01-0 is a direct alternative. For Code H systems with solder termination, the 3FA1ENHRJ-C01ER is the correct fit.","metaTitle":"Amphenol RF 3FA1ENHRJ-C01ER SMB Fakra Jack, 50 Ohm, 3 GHz","metaDescription":"Amphenol RF 3FA1ENHRJ-C01ER SMB/Fakra jack, 50 Ohm, 3 GHz, IP67, Code H, RG-174/188/316, solder contact, crimp shield, tray.
