What is a FAKRA Connector?

FAKRA connectors are standardized coaxial connectors. The acronym “FAKRA” stands for "Fachkreis Automobil," meaning "Automotive Expert Group" in German. They are widely adopted for vehicle connectivity, relying on a simple push-on mechanism to route high-frequency RF (Radio Frequency) signals for GPS, satellite radio, cellular communication, and ADAS (Advanced Driver-Assistance Systems) cameras.

FAKRA Connector Design and Manufacturing Evolution

FAKRA connectors have continuously evolved to meet the changing needs of the automotive industry, progressing from early in-vehicle systems to today’s advanced autonomous applications. Each stage of improvement has focused on enhancing RF performance, durability, and production efficiency, while maintaining compliance with global standards such as USCAR-17, USCAR-18, and DIN 72594-1.

The earliest designs used machined SMB-based contacts, delivering stable connectivity for GPS, satellite radio, and in-vehicle infotainment. Later developments introduced die-cast bodies and pre-assembled housings, lowering installation costs and improving efficiency. As demands for higher durability grew, stamped contacts and closed-entry interfaces were added for greater robustness in high-speed signal applications such as LVDS (low-voltage differential signaling) surround-view camera systems.

The most recent advancements emphasize high-speed automated production with stamped components and modular housings, enabling scalability, low latency, and high signal integrity for V2X (Vehicle-to-Everything) applications, especially safety-critical technologies like blind-spot monitoring, emergency alerts, and autonomous driving.

FAKRA Advancement Stage	Design & Manufacturing Features	Tooling Requirements	Production Scale	Compliance Standards
Foundation Advancement	Machined SMB-based body and contacts; plastic housing; easy assembly	Manual Tooling	Low Volume	USCAR-17, USCAR-18, DIN 72594-1
Cost-Optimized Advancement	Die-cast body; pre-assembled housing; reduced installation costs	Manual Tooling	Low Volume	USCAR-17, USCAR-18, DIN 72594-1
Efficiency Advancement	Die-cast body; stamped contacts; optimized design for faster assembly	Semi-Automated/Automated Tooling	High Volume	USCAR-17, USCAR-18, DIN 72594-1
Durability Advancement	Die-cast body; stamped contacts; closed-entry interface for durability	Semi-Automated/Automated Tooling	High Volume	USCAR-17, USCAR-18, DIN 72594-1
V2X Advancement	Stamped body and contacts; modular housing; supports high-speed automated production for advanced safety systems	Fully Automated Tooling	High Volume	USCAR-17, USCAR-18, DIN 72594-1, 6Q0.90.961D/E

By keeping up with these developments, ATTEND offers the latest FAKRA connector models built to meet these advanced requirements while remaining backward-compatible for legacy systems, making them a trusted choice for modern automotive and industrial connectivity.

FAKRA Connector Types Available

FAKRA Configuration

FAKRA connectors are available in various configurations to suit diverse connection needs within automotive and industrial systems:

Male (Plug) vs. Female (Jack): Male FAKRA connectors typically feature a center pin and are mounted on cables, while female FAKRA connectors have a center sleeve and are attached to devices, housings, or PCBs.
Straight vs. Right-Angle (R/A): Straight connectors allow the cable to extend directly from the connection point, making them ideal for inline connections in tight cable runs. In contrast, R/A connectors point at a 90-degree angle from the cable to optimize cable routing and strain relief, making them common in dashboard-mounted modules or crowded PCB layouts.
Cable Assembly vs. Individual Connector: FAKRA connectors can be purchased as pre-terminated FAKRA cable assemblies for ready-to-use solutions or as individual connectors for custom cable fabrication.

At ATTEND, we provide a wide range of FAKRA cable assemblies, including straight and right-angle, male and female, as well as single- or multi-port options, offering flexibility for diverse applications.

FAKRA Color Codes

FAKRA connectors use a standardized color-coding system to differentiate their functions within a vehicle’s RF and communication systems, as seen in the table below.

Each color is paired with a specific mechanical keying feature to ensure it can only be plugged into the designated port. This helps to prevent mismating while simplifying installation, maintenance, and troubleshooting. These color codes are also consistent across multiple manufacturers, allowing for interoperability.

ATTEND offers all standard FAKRA color code options, allowing engineers and integrators to select the right connector for any system:

Code	RAL No. / Color	Europe Application	USCAR Application

What is the FAKRA standard?

The FAKRA standard defines the mechanical and electrical specifications of automotive RF connectors. Compliant with ISO 20860-1/2, DIN ISO 20860, and SAE/USCAR-18, it guarantees reliable, standardized connectivity for global vehicle communication, infotainment, and safety systems.

What is the FAKRA Z connector for?

The neutral-coded FAKRA Z connector (water blue color) is a versatile universal RF interface widely adopted in automotive camera and machine-vision applications, including surround-view systems, parking cameras, and ADAS sensors. Beyond its original low-frequency signal applications, such as AM/FM radio antennas in vehicles, the FAKRA Z connector’s neutral coding provides flexibility for OEM-specific implementations, universal testing, prototype connector use, as well as applications not covered by standard color-coded variants.

What are the common problems with the FAKRA connector?

Common FAKRA connector issues include:

Loose Connections/Mismating: Occurs if the connector isn't fully seated or the locking mechanism fails due to vibration. To prevent this, make sure there is an audible "click" during installation, and use a torque wrench to tighten to the proper specification for a secure, long-lasting fit.
Bent or Broken Pins: This is often a result of improper handling during assembly. Carefully inspect pins before mating and replace damaged connectors with new, reliable ones to restore electrical contact whenever necessary.
Signal Degradation: Poor connection or insufficient shielding can lead to signal loss or interference. So, be sure to use well-shielded, high-quality connectors and ensure all components are routed away from strong electromagnetic sources.
