The 2-66100-0: Crimping is the termination method here — no solder, no insulation displacement. The 16-18 AWG range covers a common power and signal wire size in industrial and automotive harnesses. For the crimp tool, you'll want the standard TE application tooling for Multimate III+ contacts; the die set must match the stamped contact geometry to get a gas-tight connection and proper pull-off force. The tape-and-reel packaging (also available as cut tape) feeds automated crimping presses without a reel change.
Housing Compatibility and Mating
This socket contact mates with any Multimate III+ pin contact of the same series and wire range. The housing side — the receptacle that holds these sockets — is a separate order; typical Multimate III+ housings are keyed and polarized to prevent mis-mating. No secondary lock is required for most applications, but always check the housing datasheet for TPA (terminal position assurance) options if the assembly sees vibration.
