SPECIALTY TRANSDUCERS – Microphones
EK/EL SERIES
Omnidirectional (EK), Unidirectional (EL) 4.00 x 5.59 x 2.28 (mm)
EK omnidirectional microphones provide a unique combination of size, performance
and value. Its high electroacoustic sensitivity and low noise make this microphone
an excellent choice for applications where space allows. These popular microphones
are available in many model varieties.
NR SERIES
Noise Canceling 4.00 x 5.59 x 2.28 (mm)
The NR Series close talking microphones deliver state-of-the-art noise canceling performance.
NR microphones are used as headset microphones in the most demanding communication
and speech recognition environments. The NR Series microphones are available in boom
microphone packages. (See the FB Series and PNR/PWP Series for details.)
Note: All performance curves are typical
