FAKRA Aerial Connection Type List

FAKRA Aerial Connector Types

FAKRA connectors are specialised radio frequency (RF) connectors developed for automotive applications, ensuring secure and reliable high-frequency signal transmission in vehicles. The acronym FAKRA stands for "Fachkreis Automobil", which translates to "Working Group Automobile" in English, reflecting its origin with the German Committee of Automobile Manufacturers.

These connectors are based on the subminiature version B (SMB) coaxial connector design but are enclosed in a plastic housing that provides mechanical stability, colour coding, and keying to prevent incorrect connections. FAKRA connectors feature a push-on coupling mechanism with an audible click to confirm a secure connection, and many include a secondary locking system for added vibration resistance. The standard FAKRA connector operates with a 50 Ohm impedance and a frequency range from DC to 6 GHz, making it suitable for various wireless technologies such as GPS, LTE, AM/FM/DAB/DAB+ radio, video signals, satellite radio, and Bluetooth.

They are available in various configurations, including straight or right-angle body orientations, through-hole or panel mount, and with solder or crimp termination methods. The connectors are designed to withstand harsh automotive environments, with a temperature range of -40°C to +105°C. There are 14 different mechanical layouts, each associated with a specific colour and keying pattern. The only exception is FAKRA Z (water blue), which has no keying and can mate with any other FAKRA type. The standard is compliant with ISO 20860-1 and 2, DIN ISO 20860, and SAE/USCAR 18, ensuring global acceptance across major automotive manufacturers.
