The Amphenol PT series and PT-SE series connectors, based on MIL-DTL-26482 Series I standards, feature high-density contact arrangements within a circular shell. The PT series provides solder contacts, while PT-SE offers high-performance crimp contacts, and PT-CE supplies a commercial crimp option. These connectors utilize a quick-disconnect bayonet coupling for fast mating and un-mating, and are available in various mounting styles and shell sizes.
