Board-to-cable header for dense, vibration-prone builds
The 5054484071 is a 40-position, dual-row header from the Molex Micro-Lock PLUS 505448 series, with a 1.25mm pitch that keeps the board footprint tight while still allowing a 50VAC/DC rating per circuit. The shrouded 4-wall design and latch holder fastening mean the mating cable connector is guided into alignment and locked against vibration, which is the main reason this series gets specified in equipment that sees transport or fan vibration.
SMT right-angle mounting with pick-and-place readiness
The insulation height of 0.352" (8.95mm) gives clearance for the latch mechanism above the board, which is worth checking against your enclosure z-height budget before layout.
