The 1-644751-3: Unshrouded design gives direct access to the square pins for mating with MTA-156 crimp receptacles, but lacks polarisation keying — verify the mating half orientation before assembly. 13 positions in a single row suit medium-density harnesses for control panels, industrial sensors, and power distribution inside an enclosure.
The square pin profile provides reliable contact wipe during insertion.
The pitch is 0.156" (3.96mm), standard for the MTA-156 series.
Unshrouded — the square pins are exposed for direct mating with MTA-156 crimp receptacles.
A single row of 13 positions, all loaded.
Through-hole, right-angle — the pins exit perpendicular to the board for edge-mount routing.
