The TE Connectivity 2-111446-3 is a 40-position AMP-Latch IDC plug designed for mass-termination to 26-28 AWG ribbon cable. The black housing carries a feed-through feature, meaning the cable passes through the connector body and exits the opposite side — useful for daisy-chain or pass-through harness layouts where the signal continues to another connector downstream.
Termination and Wire Gauge
This is an IDC (insulation displacement connector) termination — no wire stripping, no crimping. The feed-through design means the cable runs straight through the connector body, so plan for cable exit on both sides of the plug in your harness routing.
This 40-position plug mates with the matching AMP-Latch receptacle (such as the 1-226733-4, a 17-position receptacle — note the position count difference; for a 40-circuit harness you need the 40-position receptacle half). The gold-to-gold contact interface is rated for the signal-level currents typical of ribbon cable interconnects in computer peripherals, test equipment, and industrial control panels.
