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 contact options, while the PT-SE series offers high-performance crimp contacts. Additionally, the PT-CE series includes commercial crimp contacts. These circular connectors employ a quick-disconnect bayonet coupling mechanism for rapid mating and un-mating. They are available in various mounting styles and shell sizes, making them versatile for different applications.
