The IDC slot is cut for 22 AWG wire only — no range, no adjustment. The closed-end design blocks the last cavity, preventing reverse insertion of the mating header. ## Wiring — 22 AWG Only, No Range This IDC receptacle accepts 22 AWG wire — that is the single supported gauge. The insulation displacement slot is sized for that conductor diameter; forcing a different gauge risks an open or intermittent connection. The wire type can be discrete or ribbon cable, but the gauge is fixed. ## Tin Plating — Duty Cycle Context It suits permanent or infrequent-mate harnesses where cost per position drives the choice. For applications requiring frequent disconnect or corrosive environments, a gold-plated MTA-100 variant would be the better call.","metaTitle":"TE MTA-100 3-640440-2, 2-Position IDC Receptacle","metaDescription":"TE MTA-100 3-640440-2 2-position IDC receptacle, 0.100\" (2.54mm) pitch, 22 AWG, tin-plated contacts, locking ramp.
