The TE Connectivity Sensors CM-01B contact microphone is designed for detecting subtle vibrations and sounds. It combines a sensitive PVDF piezo film with a low-noise electronic preamplifier to provide a buffered output, minimizing external noise. This microphone is ideal for applications requiring high sensitivity, such as electronic stethoscopes, bone-conducted sound pickup, and general-purpose vibration/impact sensing. Its robust construction and shielded cable ensure reliable performance in various environments.
