The 2-746610-1: The feed-through feature means the IDC termination is accessible from the top, letting you daisy-chain multiple headers on the same ribbon cable without breaking the run — useful for distributing a parallel bus or signal set across several boards.
Wiring and Termination Fit
This header accepts 26-28 AWG stranded or 26-30 AWG solid wire through its IDC slots. Termination requires an IDC press tool — no stripping, no crimping, just one stroke per cable end.
The closest functional peer in the same AMP-Latch series is the 1-216791-6, a 16-position, 2-row DIP header with the same 0.050" cable pitch and 0.100" board pitch, but in a gray housing with a slightly thicker tin finish (118.1µin vs 100µin). The choice between the two is strictly circuit count — 10 positions here vs 16 there — and color preference, with no difference in termination style, mounting, or wire range.
