The closed end acts as a positive stop for the ribbon cable, preventing over-insertion and keeping the conductors aligned with the IDC slots during mass termination. ## Termination and Wire Prep — IDC for 28 AWG The IDC termination is designed for 28 AWG wire, either discrete or ribbon cable. The closed-end housing gives a hard stop for the ribbon, so the conductors land at the same depth every time. For a harness builder, this means consistent pull-off force across all four positions without a visual inspection step. That thickness is well above the 15µin flash typically used for single-mate consumer harnesses. In a field-service or unsealed environment, the thicker gold layer resists corrosion through repeated insertions and exposure to humidity. The 3-644044-4 is the 4-position variant of the MTA-100 receptacle line. If the BOM calls for a 4-position wire-to-board connection at 0.100\" pitch, this is the receptacle that matches.","metaTitle":"3-644044-4 MTA-100 Receptacle, 4 Pos, IDC, 28 AWG, Gold","metaDescription":"TE MTA-100 4-position IDC receptacle, 0.100\" pitch, 28 AWG, gold 30.0µin contacts, locking ramp, closed end.
