USE SCENARIOS

  • Suitable for cryogenic applications
    • Because of its operating temperature ranging from –170°C to +100°C
  • Suitable for flush mounting, for example, in walls to create microphone arrays
    • Because the shape of the microphone front ensures excellent microphone performance when flush mounted. The laser-welded diaphragm on the microphone housing ensures that the sensitivity is resistant to rough handling during flush mounting
