The Amphenol PT series and PT-SE series connectors, compliant with MIL-DTL-26482 Series I standards, feature high-density contact arrangements within a circular shell. They offer different contact options: solder contacts in the PT series, high-performance crimp contacts in the PT-SE series, and a commercial crimp option in the PT-CE series. These connectors utilize a quick-disconnect bayonet coupling mechanism for easy mating and unmating, and are available in various mounting styles and shell sizes.
