4-Circuit Plug Housing for 2.00mm Pitch Wire-to-Board Harnesses
The Molex 5024390400 is a 4-position plug housing from the CLIK-Mate 502439 series, designed for wire-to-board or in-line wire-to-wire interconnects at a 2.00mm pitch. The single-row, free-hanging housing uses a latch lock to secure the mate — the audible click confirms full engagement, which matters in applications where vibration or cable strain could back a friction-fit connector out.
Contacts Not Included — Order Crimp Terminals Separately
This housing ships empty — the listing explicitly notes contacts are not included. The housing accepts non-gendered crimp terminals terminated to the wire before insertion. For a harness build, you will need the matching Molex CLIK-Mate crimp terminal (typically part of the 502439 terminal family) in the wire gauge that suits your current draw. The housing material is polyethylene terephthalate (PET), a common choice for its dimensional stability under the 105°C ceiling.
Mating Half and Harness Assembly Fit
The 5024390400 mates with the corresponding CLIK-Mate 2.00mm pitch header (typically a vertical or right-angle through-hole header from the same series). The latch lock on the plug engages with a ramp on the header shroud — no secondary retention hardware needed. The 4-circuit count matches a 4-position header on the board; the 2.00mm pitch keeps the board footprint compact enough for dense layouts while leaving room for routing between pads.
