It's the socket half of a pin-and-socket pair — you'll use it inside a Multimate III+ housing to build a wire-to-wire or wire-to-board harness.
Wiring It Up — Gauge and Termination
The 20-24 AWG range covers common signal and low-power circuits; the stamped brass body gives good spring retention in the housing cavity after crimping.
Active lifecycle — no end-of-life notice on this part number.
This socket mates with any Multimate III+ pin contact of the same wire range and fits the standard Multimate III+ housings — both the CPC (Circular Plastic Connector) and the rectangular pin-header styles. The stamped contact uses the same cavity geometry as the machined version, so you can mix stamped and machined contacts in one housing as long as the wire gauge matches. Confirm the housing part number against your BOM; the base product number 66104 identifies the contact family, and the full 2-66104-9 is the tin-plated stamped socket variant.
