Amphenol TVS06RF258B Tri-Start Circular Connector

Amphenol's TVS06RF-25-8B Tri-Start MIL-DTL-38999 Series III connector is a robust solution for demanding environments. Originally developed for military and commercial aircraft, these connectors provide high-density contact arrangements within a miniature circular shell. Key features include exceptional EMI shielding, resistance to moisture and corrosion, and the ability to operate across a wide temperature range (-85°F to +392°F). The connector's quick-mating design and environmental sealing make it ideal for applications requiring reliable interconnections in harsh conditions, such as military aircraft, commercial airlines, communications equipment, and armored vehicles. Visual confirmation of mating is provided by a plug coupling nut covering a red band on the mating shell.
