Industrial M-100 AIC Military Dynamic Microphone

Industrial M-100 AIC Military Dynamic Microphone is a MIL-PRF-26542 dynamic microphone assembly designated M-100/AIC, commonly used in rugged military headsets and intercom systems. It is specified under MIL-PRF-26542/3 for dynamic microphone assemblies and is cataloged in older references as MIL-M-26542/3. The unit uses a U-179A/U connector for field wiring, aligning with standard military microphone interconnects. In official listings and catalog references, the M-100/AIC is associated with NSN 5965-00-854-0658. The impedance for this model is commonly listed around 7 ohms, reflecting its low-impedance dynamic design suitable for headset use. Typical applications include airborne and ground communications gear, headset assemblies, and radio interfaces that require a rugged, military-grade dynamic microphone with a U-179A/U connector.
