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