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.","metaTitle":"Molex 5054484071 Micro-Lock PLUS Header, 40 Pos, 1.25mm","metaDescription":"Molex 5054484071 Micro-Lock PLUS header, 40 circuits, 1.25mm pitch, SMT right-angle, latch holder.
