What it is — series position and function
The Molex 430452424 is the 24-circuit member of the Micro-Fit 3.0 43045 series, a dual-row board-to-cable header with a 3.00mm pitch and through-hole kinked-pin solder termination. Shrouded on all four walls with a locking ramp, it carries board-lock features that anchor it to the PCB during vibration and insertion — the kind of header that stays put once it is seated in a harness or panel assembly.
Electrical and mechanical ratings
Where this class of connector is used
Micro-Fit 3.0 headers are the workhorse board-to-cable power interconnect in industrial automation, medical equipment, and telecommunications infrastructure. The 24-position count handles medium-density harness runs where a smaller connector would force a split across two cables — the 430452424 consolidates that into one mated pair with the matching Micro-Fit 3.0 plug housing. The locking ramp keeps the pair mated under cable pull and vibration; the 4-wall shrouding prevents mis-mating on adjacent positions in a dense panel.
