What is a FAKRA connector?
FAKRA is an acronym for Fachkreis Automobile which means “Automobile Working Group” in English, and stands for a standardized type of coaxial connector which is mainly used in the automotive industry. Based on SMB (SubMiniature version B) technology, these connectors are suitable for high-frequency applications of up to 6 GHz and are distinguished by their reliability and robustness.
What are FAKRA connectors used for?
FAKRA connectors are mainly used for transmitting high-frequency signals in vehicles. Typical applications include GPS systems, antennas, satellite radios and cameras. FAKRA connectors offer a safe and reliable connection which remains stable even under the extreme conditions to which they are subjected in vehicles.
What FAKRA connectors exist?
Various providers of components for FAKRA connectors exist. Major players include Rosenberger, TE, Apitv and Amphenol, but smaller companies, such as RoKA, have also established themselves on the market. The wide variety ranges from 180° and 90° outlets to sealed connectors.
How are FAKRA connectors distributed throughout the world?
FAKRA connectors have become established as standard in the automotive industry in Europe, North and South America, as well as in Korea. This standardized interface is generally preferred for global platforms. The FAKRA interface has become accepted for high-frequency transmission in China too. Initially, this took place through the import of Western automotive technology, including by joint ventures between international OEMs, such as VW, General Motors, BMW, Daimler etc., with Chinese partners such as BAIC and SAIC. Then, existing Chinese OEMs, such as Dongfeng or FAW, as well as start-ups, such as NIO, BYD or LI Auto, also started using FAKRA as an interface. In Japan, on the other hand, FAKRA connectors are not very widely used as other standards which comply with local requirements and specifications, often tend to dominate.
What is the FAKRA color coding system?
A color coding system is used for FAKRA connectors to identify the connectors’ different applications and functions. Each color stands for a specific function and is determined according to the RAL color table, e.g. a yellow connector for Ethernet connectors or a pink connector for FM radio signals. The connectors not only differ in color but also in shape. This system helps avoid confusion and guarantees the right connection.
What are the advantages of FAKRA connectors?
High-quality signal: FAKRA connectors minimize signal loss and interference which is particularly important for use in vehicles.
Easy to install: FAKRA connectors can be installed and dismantled without requiring any special tools. Their quick-lock mechanism ensures a secure hold.
Robust: FAKRA connectors withstand extreme temperatures, humidity and vibrations, which makes them ideal for use in harsh environments.
Economical: Compared with other automotive connectors, FAKRA connectors can be found in the lower price range.
What norms do FAKRA connectors comply with?
FAKRA connectors are standardized according to DIN 72594-1, USCAR and ISO 20860. These standards ensure that the connectors comply with the strict demands of the automotive industry regarding electrical and mechanical properties. This standardization ensures exchangeability and compatibility of the connectors throughout the world which facilitates integration into existing onboard networks.
What developments have been made in the field of FAKRA connectors?
Several generations of FAKRA connectors exist, from the first to the fourth generation. With each generation come further improvements in design and performance. For example, through their improved shapes and materials, generation 4.0 FAKRA connectors enable a higher degree of automation in production and, through optimized shielding and signal pathways, are even better suited to applications in driverless cars. Thanks to their reliability, standardized design and ease of use, FAKRA connectors have become an indispensable component of the automotive industry.
