Amphenol Nexus Technologies has been a long time manufacturer and qualified military supplier of airborne audio connectors, see MIL-DTL-9177. Our special ruggedized design has been the industry standard on military and commercial helmets and headsets for many years.
In addition to the mil-qualified parts, we offer a number of connector options for different mounting styles, switch functions, and soldier attachments. Electrical, mechanical, and environmental features of these connectors include:

• Environment resisting
• RFI/EMI protection
• Low-level circuit capabilities
• High cross-talk resistance

This connector design isn’t just limited to communications systems. Other markets are exploring the benefits of the quick-disconnect, rotatable connector design for harsh environments including oilfield/downhole systems and other commercial/industrial applications.
