Product details

Discrete-Wire IDC Receptacle for Harness Assembly

The TE Connectivity MTA-156 3-640426-7 is a 7-position single-row receptacle that terminates 18 AWG discrete wire directly through an IDC slot — no wire stripping, no crimp contacts, and no secondary insertion tool.

IDC Termination for 18 AWG Discrete Wire

For 18 AWG discrete wire, that means no crimp tool, no loose terminals, and one less step on the assembly line. The wire type is discrete, not ribbon cable, so each conductor is routed individually through the harness.

Mating Half and Housing Fit

The closed-end feature means the housing is fully enclosed on the wire-entry side, which keeps debris out of the IDC slot during handling. Free-hanging (in-line) mounting lets it sit anywhere along the harness without a board mount.

Frequently asked questions

What is the mating connector for 3-640426-7?

The 3-640426-7 mates with a matching MTA-156 pin header — the locking ramp on this receptacle engages the latch on the header side. The exact header part number depends on the pin count and orientation needed for your board layout.

What wire gauge does 3-640426-7 support?

It is designed for 18 AWG discrete wire. The IDC slot geometry and contact beam are sized for that gauge — using a different wire size will not achieve a reliable insulation displacement connection.
