(I)CM-01BProduct Description:

U.S.AMEAS CM-01BSeries contact microphone, pickup, vibration sensor, high sensitivity, low cost.

Cm - 0 1 bContact microphone is composed of a high sensitivity, stable performance of the piezoelectric film combined with a low noise preamplifier circuit, can provide a buffer output of sound and vibration signal pickup. In the structural design of the product, try to minimize the external noise interference, so that when the rubber pad in the middle of the product receives the vibration signal, it can output a high sensitivity signal. CM 01B is an ideal sensor for monitoring body tone.
