The Amphenol PT series and PT-SE series connectors, compliant with MIL-DTL-26482 Series I, feature high-density contact arrangements within a circular shell. The PT series offers solder contacts, while the PT-SE series provides high-performance crimp contacts; a commercial crimp option (PT-CE) is also available. These circular connectors use a quick-disconnect bayonet coupling mechanism for fast mating and unmating, and they are offered in various mounting styles and shell sizes.
