The Amphenol Airmax VS® 10028916-4554P00LF is a 4-position blade power receptacle, built for high-current daughtercard interconnects in backplane systems. It carries 80 A per circuit — each power blade is sized for bus-level current, not signal duty — and is rated 150 V. The press-fit termination means solderless assembly into a plated through-hole backplane, which avoids thermal stress on the board and keeps the connection rework-friendly.
The 10028916-4455P00LF shares the same 80 A, 150 V, press-fit, black housing, board guide, and UL94 V-0 rating.
