The 30.0µin gold plating on the mating surface handles repeated connect-disconnect cycles in field-serviceable harnesses — the gold thickness is the spec that governs reconnect duty, not the bare current rating. Brass base material gives a good balance of conductivity and spring retention in the crimp barrel. ## Mating and Housing Compatibility This pin mates with the corresponding Multimate III+ receptacle contacts and inserts into the series' standard cavity housings. The stamped construction keeps per-unit cost down for medium-to-high volume harness builds, while the gold finish ensures the contact resistance stays stable across the rated mating cycles. Crimp termination with the correct tool (typically a hand or pneumatic crimper from the TE application tooling range) is required to hit the specified pull-out force for 26-30 AWG.","metaTitle":"TE 66406-4 Multimate III+ Stamped Pin Contact, 26-30 AWG","metaDescription":"TE Connectivity 66406-4 stamped pin contact for Multimate III+ series.
