SPECIALTY TRANSDUCERS – Microphones
WP SERIES
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.)
MR SERIES
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.
