The 0.165" (4.20mm) pitch gives you a comfortable routing density for power or signal circuits up to 6A per contact at 250VAC, with the shrouded 4-wall housing protecting the pins during handling and mating.
Yes. 2-640497-2 is a header from the MR (Miniature Rectangular) series and mates with the matching MR series receptacle housings and crimp terminals. The 4.20mm pitch and latch lock are standard across the series.
This is a 2-position, single-row header. The pinout is a simple 1-to-1 pass-through: position 1 and position 2. No keying or polarity — the latch lock ensures correct orientation.
