Product details

The 20-24 AWG wire range covers the most common signal and low-power circuit sizes in control cabinets and harness assemblies. The crimp termination is a standard barrel style — the stamped contact body deforms around the stripped conductor and insulation, giving a gas-tight joint when the correct tooling is used. For a harness builder, this means the contact fits a broad range of wire without needing multiple terminal part numbers for different gauges within that span.

The 50.0µin tin plating is a robust layer for moderate mating cycle counts — think 25 to 50 cycles in a typical installation-and-service scenario. Tin contacts work well in dry circuit and low-current signal applications where the voltage is high enough to break through the surface oxide film (typically above 5-10 mV). For high-vibration environments or applications requiring hundreds of mating cycles, a gold-plated contact from the same Multimate III+ family would be the better choice, but for most panel wiring and internal harness work, this tin finish is the standard, cost-effective option.

Multimate III+ Series Compatibility

This contact is a direct fit for any Multimate III+ housing that accepts stamped socket contacts — the series includes a wide range of pin and socket housings in various circuit sizes and configurations. If you're stocking spares for a panel that uses Multimate III+ connectors, this contact is the socket-side terminal you need. Stock both halves or neither — the contact alone is useless without the matching pin contact and housing, but as a replacement terminal for an existing assembly, it's the right part.

Frequently asked questions

Where can I buy 1-66399-1?

1-66399-1 is available to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time. No stock-holding claim is made here; sourcing is per request.

Is 1-66399-1 compatible with Multimate III+ series connectors?

Yes, the 1-66399-1 is a stamped socket contact designed specifically for the Multimate III+ series. It mates with the corresponding pin contacts and fits into Multimate III+ housings that accept stamped socket terminals.

What is the wire gauge range for 1-66399-1?

The 1-66399-1 accepts 20-24 AWG wire. This covers the common range for signal and low-power circuits in control and harness applications.

What is the contact finish for 1-66399-1?

The contact has a tin finish with a thickness of 50.0µin (1.27µm). This provides good corrosion resistance for general-purpose use with moderate mating cycle requirements.
