AirMax VS® Connector

FCI and Digi-Key introduce an IMLA-based, inverse 2-piece backplane connector

AirMax VS® Connector
The AirMax VS connector from FCI is a revolutionary new connector system. The connector is a scalable, inverse 2-piece backplane connector based upon an IMLA (Insert Molded Leadframe Assembly) design that can be used for differential pair signals, single ended signals, or power - all within the same IMLA. The column differential pairs demonstrate low insertion loss and low cross-talk to greater than 12.5 Gb/s. It is available in 3, 4, and 5 pair configurations.

The "VS" in the AirMax VS connector stands for "Virtual Shield" as this unique connector design requires no interleaving shields. The elimination of these shields results in lower cost and lower weight. The end result for customers is that they can design their present systems for 2.5 Gb/s to 6.25 Gb/s and have the system grow to over 12 Gb/s without having to perform a costly redesign to their basic platform.
