The Amphenol PT series and PT-SE series connectors (MIL-DTL-26482 Series I) feature high-density contact arrangements within a circular shell. They offer various contact options, including solder contacts for the PT series, high-performance crimp contacts for the PT-SE series, and commercial crimp contacts for the PT-CE series. These connectors provide a quick-disconnect bayonet coupling mechanism for fast mating and unmating, along with multiple mounting styles and shell sizes for versatile applications.
