The 20-24 AWG range covers the most common signal and low-power circuit sizes in a Multimate III+ harness. For a harness builder, this means one contact part number covers multiple wire sizes on the same assembly — fewer line-changeovers. Gold at 30.0µin (0.76µm) is a heavy-duty plating. This thickness handles repeated insertion and extraction without exposing the brass base metal to oxidation.","metaTitle":"TE 66399-2 Multimate III+ Socket Contact, 30µin Gold","metaDescription":"TE Connectivity 66399-2 stamped socket contact for Multimate III+ series. 30.0µin gold plating, crimp termination, 20-24 AWG.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circular Connectors","Multi-Purpose Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Type":"Stamped","Series":"Multimate III+","Package":"Bulk","Wire Gauge":"20-24 AWG","Pin or Socket":"Socket","Contact Finish":"Gold","Product Status":"Active","lifecycle_stage":"unknown","Contact Material":"Brass","Base Product Number":"66399","Contact Termination":"Crimp","Contact Finish Thickness":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/6e9af5491e482232c46e0fc25458c4c7.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/66399-2/alternatives.json"},"ai":{"faq":[{"question":"What wire gauge does 66399-2 support?","answer":"The 66399-2 socket contact accepts 20-24 AWG stranded wire.
