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
  • White goods products and component testing
  • End of line testing
  • Machinery monitoring
  • Noise source location
  • Aerospace cabin and engine noise reduction
  • R&D product development
