The contact is supplied on Tape & Reel for automated crimping. Multimate III+ is TE's workhorse contact family for industrial, automotive, and appliance connectors where field-serviceable crimp contacts are specified. Use this contact in any Multimate III+ housing cavity that accepts a stamped socket — it is the crimp terminal you load into the housing before mating with the pin header or receptacle.
The gold thickness here is specified for environments where contact resistance must stay stable over many mating cycles, not for a one-time permanent crimp. The trade-off is unit cost. For a harness that mates once inside an enclosure, tin is adequate.
Packaging is Tape & Reel, which means the contact feeds into automatic crimp-and-strip machines. For hand-crimp or low-volume work, verify your tooling accepts reel-fed contacts or order cut lengths if available. The base product number is 66331, and the -4 suffix denotes the specific plating and material variant.
