M55116 & M9177 Military Audio/Radio Connectors for Mission-Critical Communication

Modern military operations demand more than clear audio—they require rugged, shielded, and mission-ready connectors that won’t fail under pressure. When supporting ground units, vehicle crews, airborne systems, or naval forces, micommunication systems depend on high-integrity connections that can withstand the elements and provide uninterrupted performance. FDH Aero is proud to supply Mil-spec military audio connectors that can get the job done.

Our M55116 and M9177 connectors are the standard across mission-critical communications because they’re ruggedized for extreme conditions and built to block out EMI/RFI interference. At FDH Aero, we stock connectors that keep your systems locked in and your teams connected.

M55116 Connectors: The Standard for Audio Interconnects
