16-Pin Right-Angle Header for Wire-to-Board Harnesses
The 1-640455-6: The single-wall shroud provides basic polarization to prevent mis-mating, though it does not fully enclose the pins like a 4-wall shroud would. For moderate-cycle applications—say, a harness that mates once during assembly and stays connected—tin is a reliable choice.
Comparing to Peer Headers
The 1-640455-6 carries 16 positions at the wider 0.100" pitch and a higher 250 VAC rating, but lacks the detent lock and full shroud. For applications needing a locking mechanism, the CT-series peer provides positive retention; for higher voltage or more circuits, the MTA-100 header is the better fit.
