Frequently asked questions
What is the 640502-3's connector series?
The 640502-3 is a member of the Molex MR (Miniature Rectangular) series — a D-sub geometry header family at 0.165" (4.20 mm) row pitch.
What is the 640502-3's listed style?
The listed style is Board to Cable/Wire — meaning this header is intended for the board-side termination of a wire-to-board or cable-to-board harness junction.
What does the 640502-3 mate with?
It mates with the matching MR-series shrouded receptacle housing that accepts the 4-wall shroud and latch-lock profile. The connector is a 12-position 3-row male pin header — the mating half must carry the corresponding 12-way female contact array and latch tab.
