6-Position Header, 5 Loaded — One Cavity Open
The 643494-3 is a 6-position MTA-100 header with only 5 positions loaded — one cavity is intentionally left empty, which matches the standard MTA-100 receptacle that also skips that position for keying or circuit omission.
Friction Lock Mates with MTA-100 Receptacles
The integral friction lock (fastening type) engages the matching MTA-100 crimp receptacle housing, providing vibration-resistant retention without a separate latch or screw.
