SPECIALTY TRANSDUCERS – Microphones
WP SERIES
– Waterproof Microphone
Omnidirectional, Noise Canceling 4.00 x 5.59 x 2.28 (mm)
Knowles’ waterproof microphones survive immersion in water. The WP Series’ form
factor is a very small size with low vibration sensitivity. The excellent noise canceling
performance is useful for sensors and instrumentation. The WP Series are available in
boom microphone packages. (See the FB Series and PNR/PWP Series for details.)
Waterproofed to submersion in 1m water
Close-talking (noise-canceling)
Corrosion resistant
Withstands explosive decompression
Excellent environmental performance
High resistance to mechanical shock
Sensitivity @1kHz

MR SERIES
– Waterproof Microphone
Omnidirectional 22.12 DIA x 9.3 (mm)
The MR Series Assemblies consist of a microphone element attached to
a waterproof bellows assembly. They may be panel mounted, attached for
boom applications, and are suitable for outdoor use or repeated submersion.
Highly waterproof – no loss of performance after immersion
in 15-20 m water
Corrosion resistant
Withstands explosive decompression
Design proven in rugged environments
Cable wire attached
High resistance to mechanical shock
Acoustically transparent bellows
Resists effects of mud, sand, and salt encrustation
