FAKRA SMB Plug: C-Code, Beige (RAL 1001)
- Complete with housing, pin, body, ferrule and heatshrink.

The automotive industry has been revolutionized with the increased adoption of telematics in vehicles including GPS, Cellular, Bluetooth and Satellite Radio. No longer are satellite navigation systems and sophisticated in-vehicle entertainment confined solely to the luxury end of the market.

As telematic advancements become more reliable, available and inexpensive, vehicles are transforming into an intelligent platform for enabling mobile life. With these recent advancements in communications technology and increased consumer demand for a diverse array of on-board telematics services, RF communications systems have become integral components of today’s automobile, trucking, watercraft, motorcycle and off-road construction markets. To keep RF interconnection costs low, and to ensure high levels of electrical and mechanical performance for telematics applications, such as Global Positioning Satellite, Satellite Radio, Vehicular Internet Access, Remote vehicle diagnostics and Bluetooth, the worldwide automotive industries have standardized a high-performing, cost-effective RF connector based on the FAKRA standard.

Utilizing a modified metal SMB connector embedded within a plastic housing that can be designed with multiple color codes for easy identification, FAKRA connectors are designed to perform up to 6 GHz and meet the particular mechanical and environmental requirements of the automotive industry.

FAKRA Generation 1.0 & 2.0

fakra generation diagram

Generation 1.0: Utilizes a modified metal SMB connector embedded within a plastic housing unit for ease of identification and assembly. These plastic housings are designed with visually and mechanically coded and keyed tooling to eliminate assembly errors. Standard FAKRA connectors are designed to perform up to 6 GHz and meet the electrical, mechanical and environmental standards of the automotive industry. Generation 1.0 typically features five separate component parts.

Generation 2.0: Offers reduced installation costs for our customers via a pre-assembled housing unit. This pre-assembled housing eliminates two loose components and their associated assembly and handling costs. Due to this component reduction, Generation 2.0 features three separate components to install versus Generation 1.0’s five separate components.
