MIL-DTL-26482 Miniature Circulars

Widely used in aerospace applications, TE’s MIL-DTL-26482 Standard Series II miniature circular quick disconnect bayonet coupling , also known as DEUTSCH AFD Series Connector, is widely used on applications requiring general-purpose, miniature cylindrical bayonet coupling connectors. It is environmentally sealed and offered in four receptacle-mounting styles including: narrow and wide flange wall-mounting, cable connecting and jam nut mounting receptacles. Designed to eliminate failure modes characteristic of many previous devices, TE’s MIL-DTL-26482 Standard miniature connector stands out as a reliable connector for aerospace environments.
