PUI Audio Microphone, 4mm Length, - DMM-4326-T-WP-R
This microphone is a miniature MEMS omnidirectional sensor designed to capture audio in Compact electronic assemblies. It operates from a low-voltage supply and delivers a broad audible frequency range suitable for voice and environmental sound detection in automation and embedded electronics. The device uses a pin-type connector and does not include a cable, making it straightforward to integrate into custom harnesses or PCB-mounted solutions.
Features and Benefits:
• Omni-directional pick-up pattern for uniform sound capture across angles
• Sensitivity -26dB enabling detection of low-level acoustic signals
• Operates from 1.5 to 3.6V supply for flexible power designs
• Frequency response from 20Hz to 15kHz for voice and environmental audio
• Pin-type connector for straightforward board or harness connection
• RoHS and REACH compliant for regulatory material considerations
• Sensitivity -26dB enabling detection of low-level acoustic signals
• Operates from 1.5 to 3.6V supply for flexible power designs
• Frequency response from 20Hz to 15kHz for voice and environmental audio
