The Molex 0782131044 is a 4-position power header from the Impact 78213 series, built with male blades in a 2-row layout. It's a dedicated power interconnect — all four positions are loaded as power contacts, so there's no signal mixing here. The press-fit termination and right-angle board-edge mounting mean it's designed to plug into a backplane or mid-plane, carrying DC rail current perpendicular to the PCB.
Termination and Mounting — Press-Fit, No Solder
This header terminates with press-fit pins, meaning it gets pressed into plated through-holes on the board — no solder wave, no reflow. That's a clean assembly for high-reliability backplane builds where rework needs to be straightforward. That saves vertical space inside the enclosure and keeps the power harness routed along the board plane.
