FAKRA Connectors are designed for automotive applications and are based on the SMB connector interface and comply with the standard for a uniform connector system established by FAKRA (FACHARBEITSKREIS AUTOMOBIL – German group of experts from vehicle manufacturers and equipment suppliers). Due to their special standard locking system FAKRA connectors fulfill the high functional and safety requirements of today’s automotive industry and are specified for 6 GHz in 50 omh or 60 ohm. These connectors are commonly used in GPS antenna, Engine management system, Analog/Digital radio, Auxiliary heating, TV/Video-displays, Antenna, Distributor box, Accident data analysis, Mobile phone, Remote control keyless entry, Distance control, Air pressure control, and Navigation systems.
The connectors are equipped with a standardized coding system which permits easy and fast assembly using fourteen possible coding options. The locking system has primary and secondary locking to prevent inadvertent detachment.
The FAKRA standard is described today in the DIN 72594-1 / ISO 20860-1 and harmonized with the USCAR-17 standard and the goal is to transfer the DIN and USCAR standard into an international ISO standard. USCAR-17 is meanwhile replaced by ISO 20860-1 and the same will happen with DIN 72594-1.
- Sophisticated mechanical and color coded system with 14 different codes
- Continuous strip mounted, stamped and formed center contacts ensure efficient automatic assembly
- High mounting security:
- Pre-assembling locking features ensures correct position of the coaxial insert in the coded housing
- Secondary locking feature prevents incorrect mating
- Secure primary locking system between plug and jack with tactile and audible locking mechanism
- Protection frame and protection strip protect against accidental demating
- Coaxial insert and cable can be rotated freely 360° in coded housing
- Secure secondary locking with high axial retention force of the coaxial insert in the coded housing
- Shock and vibration proof housing protects coaxial insert
- Cable types with fixing groove for chassis mounting
