Product details

It mates with any Multimate III+ socket contact in the corresponding housing cavity, making it a drop-in terminal for the full series.

The 20-24 AWG wire range covers the most common signal and low-power circuit sizes in harness assemblies. The crimp termination gives a gas-tight connection when paired with the correct TE application tooling — the stamped contact body is designed for a specific crimp height that maintains pull-force above the wire tensile strength. For a 24 AWG wire, the crimp barrel closes fully without excess void; for 20 AWG, the insulation support grips without crushing.

Compatibility across the Multimate III+ system

The key constraint is the wire gauge: the contact barrel is sized for 20-24 AWG, so a housing requiring a larger or smaller wire needs a different contact variant. No special adapter or insert is needed; it crimps and inserts with standard Multimate III+ tooling.

Frequently asked questions

Is the 66400-4 pin contact compatible with all Multimate III+ housings?

Yes — the 66400-4 is a standard stamped pin contact for the Multimate III+ series and fits any housing cavity designed for that contact family, provided the wire gauge is within the 20-24 AWG range.

What wire gauge range is the 66400-4 compatible with?

The 66400-4 accepts 20-24 AWG wire. The crimp barrel and insulation support are sized for this range; using wire outside it will not achieve the specified pull-force or contact retention.
