Board-fit and mating system
The 3-647166-2: This is a 2-position, single-row, shrouded header from the MTA-100 series, surface-mount soldered to the PCB. The friction lock on the shroud holds the mating receptacle in place under cable strain or vibration — a practical detail for harnesses that see movement or routing in an enclosure.
The 0.100" pitch and single-row layout are consistent across the series.
