FAKRA and HSD plug connections
Introduction
Every year, the German automobile manufacturers and deliverers worldwide invest billions of Euro in research and development. Today, the electrical sector and especially the automotive branch have elementar importance to manufacture internal communication connections in vehicles. In every factory, no matter if BMW, Audi or Ford, FAKRA and HSD are common technologies to connect elements of electrical engineering with each other.
Forerunner and developer of the HSD technology is the German company Rosenberger Hochfrequenztechnik GmbH & Co. KG (Rosenberger High frequency technology) which researches and develops not only high-frequency automotive connectors but also is active in other areas of mechanical engineering.
With its diverse plug connections, the developers of FAKRA and HSD plugs and jacks have create an almost error-free solution to makes it easier not only for factory workers but also for hobbyists. No matter if FAKRA or HSD, Red matches only to Red, and Black only to Black... For both technologies applies, only the color code Water blue is a universal solution and can be adapted to all colors.

FAKRA - What is it?
FAKRA is a plug connection system especially developed for car electronics. You can find it, amongst others, in the area of GSM mobile service and GPS antennas, and it serves for transfer of camera data. The name of the specification according to DIN 72594-1 and USCAR-18 generates from FAchKReis Automobil (specialist group automobile) of the company Rosenberger.
With up to thirteen different color-coded and appropriate mechanically coded markings, the FAKRA plug and jack are secured against plugging mistakes. The codes are made for different signal types and applications. They have guide notches and can be used only for a specific signal type. The fourteenth color FAKRA Z Water blue is neutrally coded and universally applicable.

FAKRA application areas
Today, FAKRA plugs are largely used to run antennas. In modern vehicles, there are mostly several antennas which make sure that the radio or GPS reception behind trucks or in radio dead zones will not be interfered or even disrupted. If two or more antennas are installed in the vehicle - for example in the sky, on the bumper or the rear window of the vehicle - this is known as antenna diversity.

1 Mounting groove for cable connectors for chassis mounting
2 Secure primary locking system between plug and coupler with tactile and audible locking
3 Protection bars and protective strips prevent unintentional opening of the primary latching arm
4 Protection of the coaxial insert by shock and vibration resistant coded housing
5 Secure secondary locking with high axial retention force of the coaxial insert in the plastic housing
6 Sophisticated mechanical and colour coding system with 13 different codes
Technological classification FAKRA
FAKRA is based on the SMB connector technology from the family of connectors for coaxial cables in the high-frequency range. The abbreviation SMB stands for Sub-Minature-B. SMB connectors for mostly device-internal connections are used for frequencies up to 6 GHz. They are plugged and not screwed, like SMC connectors, for example. The FAKRA connectors are suitable for cable types RG58, RG174, RG316, RG188 and others.

HSD - What is it?
HSD stands for High Speed Data and is a 4-pin interface that can be used to create shielded high-speed connection systems. The interface is designed based on the "star-four principle", which means that the opposite wires form a wire pair.

Advantages of the HSD interface
Thanks to the star-four principle, HSD technology firstly creates internal error safety by preventing the so called crosstalk. On the other hand, external interferences are avoided.
Like FAKRA shown above, HSD is also a plug-in connection system. The mounting of components and modules can be made fully automatical and so in comparably short time. The HSD module is twofold secured, primarily and secundarily. A high cable pull-off force, coding efficiency and contact safety, are further advantages of the plug system.
HSD application areas
As included in the name, HSD serves the high speed data transfer. In addition to the interference safety just described, HSD offers high signal quality, which is why its main area of application is the automotive industry.
- connects components of electrical engineering and electronics in vehicles
- offers connection solutions for vehicle infotainment modules, camereas, device connectors for vehicle occupants and screens
- creates connections für driver assistance
HSD connector systems can transmit USB signals, signals from LVDS cameras or from IEEE 1394. This makes HSD suitable for digital infotainment applications or head-up displays, HD entertainment, symmetrical networks, Ethernet data connections, telematics, video transmission via GVIF and also mobile phone base stations.
Technical specification HSD
For signal transmission, HSD uses the LVDS protocol (Low Voltage Differential Signaling). It is compatible with ethernet and USB protocols (as for example USCAR 30, Mini USB). With an impedance of 100 Ohm, a data transfer rate up to 1.6 Gbps is possible. In addition, long distances with cable lengths up to 10 meters are bridgeable.
The HSD connector system can be encoded with color mechanical coding devices and is suitable for the various bus concepts in automotive technology, such as the MOST bus, LIN and CAN bus and APIX, as well as for Ethernet and Mobile High-Definition Link (MHL).
The system has more than 10 different male types which are marked by colors and so make mistakes while plugging impossible. Thanks to the guide notches, the modules cannot be interchanged. The connector is equipped with a snap lock and has a stable plastic housing. Like at FAKRA, the HSD Z code (Water blue) is universally applicable.
