M55116 Mil-Spec Connectors

Amphenol Nexus Technologies manufactures the complete line of qualified MIL-DTL-55116 five and six pin audio connectors.
This encompasses waterproof, polarized plugs and receptacles for use in audio frequency circuits at 60 volts maximum potential and 0.5 amperes maximum current.
Connectors can utilize either crimp sleeve or solder cup contacts. The rigid contacts in the plug connectors mate with the pogo-pin, or spring-loaded, contacts in the receptacle.
Plugs come with a wire strain relief or molded strain relief. Receptacles are available in either panel-mount or an in-line receptacle.
Connector options, such as shielding, filtering, right-angle connectors, and miniaturization of M55116 products are available.
These connectors are used throughout military radio systems and intercom systems for ground, vehicle, airborne, and naval communications.
