FAKRA is an acronym for Fachkreis Automobile or Working Group Automobile. These versatile connectors are in widespread use in the global automotive industry, primarily in telematics, safety, and communications applications. An average connected car contains at least 15 FAKRA connectors.
The FAKRA standard defines the connector’s interface and mechanical and electrical characteristics. FAKRA cables consist of a plug jack and cable that mate via a push-on mechanism embedded within a plastic housing. An audible locking confirmation lets operators know a connection has been made. Some variations include a secondary lock. They are available in 14 different mechanical layouts. Color-coding enables easy identification and prevents mismatching. FAKRA cables can operate up to 6 GHz.
FAKRA cables are used throughout automotive vehicles in applications such as telematic and GPS navigation, entertainment systems, Bluetooth, cellular, keyless entry, climate controls, and radio antennas. They are also used in sensor systems for autonomous controls. Other non-auto applications include outdoor routers, industrial process control boxes, machine-to-machine modules, and IoT devices.
There are several subtypes of FAKRA cables: The original FAKRA I connectors are now primarily used in antenna applications. FAKRA II, the second generation of FAKRA, is considered the current base standard. They are available in a variety of angles and configurations, including an IP6K9K sealed and weather-resistant version for use in outdoor applications. Customized and miniaturized versions are available from some manufacturers.
