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 26-28 AWG ribbon cable is pressed into the slot, and the contact displaces the insulation to make connection. 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.
Mating and Compatibility
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.
