Model 377A60 Random Incidence Microphone with Sensitivity of 50 mV/Pa


January 23, 2006, Depew, NY, USA - The Vibration Division of PCB Piezotronics, Inc. (PCB) introduced Model 377A60 externally polarized, 1/2" Random Incidence (Diffuse Field) type microphone. The distinguishing feature of this model is its enhanced sensitivity of 50 mV/Pa. It has wide dynamic range (15 to 146 dB (A) re 20mPa) and a frequency range from 3.15 Hz to 10,000 Hz (+/- 2 dB). This traditional type condenser microphone has a +150 C (+302 F) operating temperature range, and -when combined with the PCB Model 426A30 preamplifier -can operate from a 200 V power supply for externally polarized microphones. This traditional-style microphone preamplifier terminates in a 7-pin LEMO style connector.


In addition to its traditional 200V models, PCB carries a full line of modern, pre-polarized, condenser microphones and preamplifiers. Powered by a 2 to 20 mA signal conditioner and standard coaxial cables, these modern designs allow for significant savings in power supply and cabling cost, greater ease-of-use and operate from the same power required for ICP accelerometers. This provides the advantage of using microphones with ICP accelerometers in the same test, with the same signal conditioning equipment, minimizing set-up time.
