The 0.156\" (3.96mm) pitch matches the MTA-156 header family — the same pitch used across the series for board-to-wire power distribution inside equipment enclosures. The orange housing colour is the standard MTA-156 moulding; the closed-end design and polarizing key prevent inserting the wrong header or reversing the orientation on the line. ## Termination and Wiring — IDC for 18 AWG This is an IDC (insulation-displacement) receptacle, not a crimp — the wire is pressed into a slot that cuts through the insulation and grips the conductor. The slot is sized for 18 AWG stranded or solid wire, which is heavier than the 22-24 AWG typical of signal IDC connectors. That makes this part suited for low-current power runs inside a panel or appliance where you want a solderless, gas-tight termination. The free-hanging (in-line) mount lets it float in the harness rather than locking to a panel. ## Contact Plating — 30.0µin Gold for Repeated Mates That is well above the 15µin flash grade — this receptacle is specced for repeated mating and unmating cycles without the contact fretting you would see with tin plating. If your harness gets disconnected during field service or test, the gold pays for itself in contact reliability. The base metal under the gold is not stated, but the gold thickness alone tells you this is not a one-time-crimp-and-forget part.","metaTitle":"TE MTA-156 3-644460-2 Receptacle, 2 Pos, IDC, 18 AWG, Gold","metaDescription":"TE Connectivity MTA-156 3-644460-2 receptacle, 2 positions, 0.156\" pitch, IDC termination for 18 AWG wire, gold contacts.
