Instructions
With recent advancements in communications technology and increased
consumer demand for a diverse array of on-board telematic services, RF
communications systems have become indispensable components of the
modern automobile.
To keep RF interconnection costs low and ensure high levels of electrical
and mechanical performance for telematic applications, the German and
American automotive industries have standardized a high-performing,
cost-effective RF connector based on the FAKRA and USCAR standards.
Utilizing a standard metal SMB connector embedded within a plastic housing that can be designed
with multiple colored codes for easy identification, FAKRA connectors are designed to perform up to
4GHz and meet the particular mechanical and environmental requirements of the automobile
industry.
Amphenol offers both its original FAKRA connectors, which incorporate machined components, as
well as its FAKRA II connector series which utilizes die cast as well as stamped and formed
components.
