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. They include solder contact options, with the PT-SE series offering high-performance crimp contacts and the PT-CE series providing a commercial crimp option. These circular connectors utilize a quick-disconnect bayonet coupling mechanism for fast mating and unmating, and they are available in various mounting styles and shell sizes.
