Amphenol RF FAKRA Automotive Connectors

Amphenol RF FAKRA Automotive Connectors are designed to perform up to 6GHz and meet the particular mechanical and environmental requirements of the automotive industry to ensure reliable communication inside, to, and from vehicles. Amphenol RF also offers a variety of FAKRA connectors for PCB and antenna interfaces, as well as mixed dual coax/power FAKRA connectors. Amphenol RF FAKRA connectors comply with USCAR 17 and 18. Utilizing a modified metal SMB coaxial connector, the (female) jack features a closed-entry interface with a protected outer contact, making the connector more robust than traditional SMBs. These FAKRA connectors are embedded within a plastic housing that features multiple color codes for easy identification and unique keying to prevent mismating.
