What This DuoPlug Receptacle Does in the Harness
The TE Connectivity DuoPlug 2-284932-4 is a 4-position, single-row receptacle that terminates flat ribbon cable or discrete wires via IDC (Insulation Displacement Connection) — no stripping, no crimping. It accepts 22-24 AWG wire and uses tin-plated female blade socket contacts. The free-hanging (in-line) body lets it sit in the middle of a harness or at the end of a cable run, mating directly to a PCB-mounted header.
IDC termination saves a step in harness assembly. For 22-24 AWG, the slot geometry is sized to hold the wire without cold flow or intermittent contact.
