PT02A-8-4S Circular MIL-Spec Connector

The PT02A-8-4S is a 4-position circular receptacle connector with female socket contacts, designed for rugged electrical interconnect applications in aerospace, military, transportation, and industrial systems. It is part of the PT Series compliant with MIL-DTL-26482 Series I, a family of miniature cylindrical connectors known for compact size, high reliability, and durability in harsh environments. 

This connector features a panel-mount box receptacle design with solder-cup terminations, allowing secure wire connections in cable harnesses or equipment enclosures. A bayonet coupling mechanism provides quick, secure mating with compatible plugs while maintaining strong resistance to vibration and mechanical stress.

The aluminum shell with olive-drab cadmium finish ensures excellent corrosion resistance and durability, while the neoprene insert provides insulation and environmental protection for the contacts. These characteristics make the PT02A-8-4S suitable for high-reliability signal or power connections in demanding operating conditions.
