Condition:New
Type:Logic ICs
Model Number:CM-01B
Supply Voltage:5V
Applicable scenarios:Medical, scientific research
Working principle:Vibration sensor
Product description：The CM-01B contact PVDF sensor is composed of a
piezoelectric film with high sensitivity and stable performance combined with a
low-noise preamplifier circuit, which can provide a single sound and vibration
signal pickup in a buffered output manner. In the structural design of the
product, try to reduce 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 a suitable sensor for monitoring body sound.
Feature:
High
sensitivity, stable performance, low noise, piezoelectric film technology,
shielded wire lead out, robust and durable, wide frequency band, good impact
resistance, light weight and low cost
Application
? Electronic stethoscope
? Bone conduction pickups
? Universal contact microphone
