Board-edge harness header for MTA-156 receptacles
The 1-640387-6 is a 16-position, single-row header from TE's MTA-156 series, pitched at 0.156" (3.96mm) and terminated through-hole, right-angle to the PCB.
Right-angle footprint and mating lock
The 0.125" (3.18mm) post length is the solder tail that goes through the PCB; the 0.400" (10.16mm) mating pin length provides enough wipe for the receptacle contacts. The friction lock is integral to the shroud — no separate hardware needed, and it audibly clicks when fully seated.
