The 5054481071 is a 10-position, 2-row header from the Molex Micro-Lock PLUS 505448 series, designed for board-to-cable/wire connections at a 1.25 mm pitch. It terminates via solder to the PCB surface mount, right-angle orientation — the mating axis runs parallel to the board, which saves height in tight enclosures.
Pitch is 0.049" (1.25 mm) — dense enough for compact designs but still routable on standard PCB layers without micro-vias. Voltage rating is 50 VAC/DC; current rating varies by wire gauge, so the limiting factor is the wire size in the crimp terminal, not the header contact itself. The header is fully shrouded on all four walls, which protects the male pins from damage during mating and prevents misalignment.
