The Amphenol PT series and PT-SE series connectors (MIL-DTL-26482 Series I) feature high-density contact arrangements within a circular shell. PT connectors provide solder contacts, while PT-SE models offer high-performance crimp contacts, and PT-CE options include commercial crimp contacts. 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.
