SPECIALTY TRANSDUCERS – Microphones
FG/DFG SERIES
Omni-Directional (FG), Directional (DFG) 2.56 DIA x 2.56 (mm)
The FG Series microphone is the world’s smallest electret condenser microphone.
Its cylindrical shape and compact size facilitate compact designs. The FG can
also be used in directional applications as a matched omni-directional pair.
EM SERIES
Omni-Directional 3.63 x 3.63 x 2.28 (mm)
The EM is a popular, alternative omni-directional microphone. The EM can also
be used in directional applications as a matched omni-directional pair.
Note: All performance curves are typical
