Microphones
Waterproof
• Highly waterproof and submersible
• Withstand explosive decompression
• Excellent environmental performance
• Corrosion resistant
Knowles’ waterproof microphones are designed to survive complete immersion in water. Form factors include a miniature design that can be immersed in water to a depth of one meter, and a bellows design for depths to 15 meters. The bellows design may be panel mounted and is suitable for outdoor use and repeated submersion. The miniature design offers excellent noise canceling performance that is ideal for underwater sensors and instrumentation.
MR Series
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.
