About MIL-DTL-26482 Series 1 Connectors

MIL-DTL-26482 Series 1 solder connectors form the foundation for many military and industrial interconnect applications. The series features heavy-duty connectors with solder contacts and bayonet or “quick-disconnect” coupling.

MIL-DTL-26482 features bayonet “quick-disconnect” coupling, making connecting and disconnecting quick and easy!

MIL-DTL-26482 Series 1 connectors are rated to IP67. Environmental sealing is achieved with a grommet and clamp design. Operating temperature for the connectors is from –55° to +125°C. Operating voltage is 1,000 VAC (RMS) at sea level.

The series offer pin and socket contacts that are machined from low-loss copper alloy and are gold plated to eliminate contact corrosion and provide an indefinite shelf life. All connectors have resilient inserts that provide high dielectric strength and a good moisture barrier. A variety of shell finishes (including non-cadmium) and a variety of accessories are available to ensure interconnect reliability.

MIL-DTL-26482 Series 1 Connector Shell Styles

MIL-DTL-26482 Series 1 connectors are IP67 rated for applications in harsh environments. Aerospace-grade aluminum shells provide heavy-duty protection while a standard olive drab cadmium finish provides excellent corrosion resistance. Alternate finishes (including RoHS) are available.

Select your preferred shell style from the list below:



Straight Plug

The MS3116 plug is compatible with all MIL-DTL-26482 Series 1 receptacles. Backshells are available to meet a variety of service class requirements. Always use a protective cover when plug is disconnected to protect contacts from environmental contaminants and impact.

Jam Nut Receptacle

The MS3114 jam nut receptacle provides increased environmental protection due to its single mounting hole design. An integrated silicone O-ring offers additional sealing. A protective backshell is recommended if the connector is subjected to environmental hazards. A cover should be used to protect the contacts from damage.

Cable Mount Receptacle

MS3111 in-line or cable mount receptacles are used for extension cord applications. A reduced flange with rounded corners protects the connector from impact when the attached cable is dragged or dropped. A protective backshell is recommended if the connector is subjected to environmental hazards. A cover should be used to protect the contacts from damage.
