Board-to-Cable Fit: Pitch, Positions, and Plating
The 2-640500-4: This is a 6-position, 2-row shrouded vertical header on 4.20 mm pitch, rated 6 A per circuit with gold-plated mating contacts. The tin-plated posts (150.0 µinch) handle the solder joint without compromising the mating surface.
Mating Half and Harness Build
This header mates with a corresponding MR series receptacle housing (sold separately). The 4.20 mm pitch and latch lock are common across the family — confirm the receptacle's circuit count and keying match your harness. The crimp terminal for the receptacle accepts wire gauges per the terminal datasheet; the header itself terminates via through-hole solder to the PCB.
