Externally polarized microphones set the initial standard for all acoustic test and measurement applications. They rely on a dedicated 200V power supply and specialized cables with 7-pin LEMO® connectors. Their straightforward design supports a wide product range. Often chosen as replacements for existing models or when prepolarized alternatives are unavailable.
  
    Highlights:
    
      - Operates from 200V power
 
      - Interchangeable with other manufacturers' externally polarized models
 
      - Large assortment of sizes and models
 
      - IEC 61094-4 WS2F compliant
 
      - Designed to be used in IEC 61672 Class 1 compliant systems
 
    
   
  
    Applications: 
    
      - Environmental noise monitoring
 
      - Automotive Noise, Vibration, Harshness (NVH) tests
