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.","metaTitle":"TE Connectivity 66400-4 Multimate III+ Stamped Pin Contact","metaDescription":"TE Connectivity 66400-4 stamped pin contact for Multimate III+ series.
