The stamped construction keeps the contact cost low for high-volume harness production. ## Plating Grade — Tin-Lead at 50.0 µin Tin-lead is a traditional choice for power contacts where the mating force is higher and the plating needs to resist galling.","metaTitle":"TE Connectivity 66399-6 Multimate III+ Socket Contact","metaDescription":"TE Connectivity 66399-6 stamped socket contact for Multimate III+ series.
