9-circuit plug, 5.00 mm pitch, screw termination
The 0395237009 is the 9-position member of Molex's Eurostyle ESE 39523 plug family, a free-hanging female socket strip at 5.00 mm pitch.
Wire entry and retention latches
The plug wire entry is angled at 270°, which routes the cable exit parallel to the mating face — useful when the wire bundle needs to run along the board or panel after the connection is made. Retention latches on the non-wire side hold the plug to the mating header; the insulation height of 1.020" (25.91 mm) gives clearance for the latch mechanism and the screw access.
