This is the smallest circuit count in the series — a two-position connector for simple power or signal taps where only a single pair of wires is needed. The yellow housing is a visual identifier, not a functional spec — useful for color-coding a specific circuit in a multi-connector harness, such as an always-hot line or a safety interlock. The closed-end feature means the back of the housing is sealed, preventing wire push-out and providing a clean termination face. ## Wire Gauge and Cable Compatibility This receptacle accepts 20 AWG wire only, in either discrete or ribbon cable form. For ribbon cable, the 0.156\" pitch matches standard 0.156\"-center ribbon, so the conductors align directly with the IDC slots without staggering. The receptacle is free-hanging (in-line) with no mounting ears — it mates with the corresponding MTA-156 male header (through-hole or vertical). The closed-end back prevents the wires from pushing through during termination or handling. No secondary locking feature is listed; the IDC retention holds the wire in place once terminated.","metaTitle":"TE MTA-156 3-640432-2, 2-Pos IDC Receptacle, 0.156\" Pitch","metaDescription":"TE Connectivity MTA-156 receptacle, 2 positions, 0.156\" pitch, IDC termination for 20 AWG discrete or ribbon cable.
