The 644518-4: The shrouded 1-wall design provides basic polarization to prevent mis-mating. A friction lock on the header body secures the mating receptacle, offering retention in applications with moderate vibration.
This header mates with MTA-100 crimp receptacles (e.g., 640441 series) using the friction lock for retention.
