The Molex 0430452412 is a 24-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire interconnects. The 4-wall shrouded housing with a locking ramp provides mechanical retention and protection against mis-mating in applications like automotive, industrial, medical, and telecom systems.
The locking ramp and 4-wall shrouding mean this header is designed to stay mated under vibration — the latch gives an audible click, and the shroud prevents contact damage during blind mating.
The 24 positions are all loaded in a dual-row configuration with 0.118" (3.00 mm) row spacing. The kinked solder tails (0.125" post length) provide retention in the plated through-holes during wave soldering.
