MR-23151-000

Home / Products / Acoustic Components / Microphones / Specialty Microphones / MR-23151-000

MR Series microphones combine a conventional element with a waterproof bellows assembly. The bellows conducts sound to the element and survives 15m (50 feet) of submersion in water. They may be panel mounted, attached for boom applications and are suitable for outdoor use or repeated submersion.

Hundreds of legacy design possibilities can be applied to your product challenge with our electret microphones. Ideal for products that require premium audio and very small form factors, solutions include noise canceling, omni-directional and unidirectional performance. Other variables include size, shape, amplification, sensitivity, low noise, and resistance to vibration and mechanical shock.

  • Wide range of size and performance options
  • Magnetic and waterproof
  • Low noise and RF filtering versions
