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
