FAKRA Cable Assemblies
FAKRA — from Fachkreis Automobil, the German automotive working group behind it — is the car industry's coded coaxial connector: an SMB-based 50 Ω interface in a plastic housing whose color and key, the code, let a plug mate only with a jack of the same code. It carries antenna signals and camera links in vehicles, and more and more on robots, machine-vision cameras and field equipment. FAKRA lines are quoted either as assemblies built to your drawing by our manufacturing partner or as finished cables sourced by part number, and the quotation says which.
Where FAKRA assemblies are used
Vehicle cameras and antennas
Camera, GNSS, radio and telematics antenna leads, each end coded to the module it plugs into.
Robots and machine vision
Camera links on mobile robots, humanoids and inspection systems, GMSL cameras among them.
Field and fleet equipment
GNSS and cellular antenna leads on agricultural machines, telematics units and outdoor equipment.
What you can specify
Each point is confirmed with our manufacturing partner before the quotation. Connectors are the genuine parts your drawing names, and an alternative is used only with your written approval.
- The code at each end, matched to the device's socket
- Plug or jack, straight or right-angle, cable or panel mount
- Cable — RG174, RG316 or a lower-loss 50 Ω coax for longer runs — and length
- The far end: FAKRA, Mini-FAKRA (HFM), SMA or another RF connector
- Sealed versions where the connector sits outdoors or gets washed down
- Labels naming the signal at each end
Testing and records
Every unit is continuity tested and ships with a test report. RF measurements such as insertion loss or VSWR are never assumed: if your link needs them, say so in the RFQ, and whether and how they can be measured is confirmed before the quotation.
On a FAKRA lead the continuity test checks the center conductor and the shield end to end, and that the two never touch.
How testing and records work →Common questions
What do the FAKRA codes and colors mean?
Each code is a color and a mechanical key on the housing. A plug mates only with a jack of the same code, which keeps a camera lead out of an antenna socket; the water-blue Z code is neutral and mates with the others. Send the code of the socket each end plugs into.
Do you build FAKRA cables for robots and machine vision, not only vehicles?
Yes. The same connectors carry camera and antenna links on robots, inspection cameras and field equipment, and they are quoted the same way: to your drawing, with the code, cable and length you specify.
Can you make FAKRA to SMA adapter cables?
Yes — a FAKRA end on one side and an SMA, Mini-FAKRA or other RF connector on the other is a common request, built to your drawing or sourced by part number.
What should a FAKRA cable RFQ include?
The code and gender at each end, straight or right-angle, the cable type and length, sealing if the connector sits outdoors, the signal it carries — camera, GNSS, radio — and quantities.
