ACMQ9745CP1033-22

RYD ACMQ9745CP1033-22 is a Φ9.7×4.5mm omnidirectional electret condenser microphone with exceptional -22±3dB sensitivity and 50Hz–20kHz wide-band response for far-field IoT voice and acoustic sensing. Maximizes signal level at distance for large-area voice activation, perimeter acoustic monitoring, and sparse-microphone IoT deployments. 60dB SNR maintains usable noise floor despite high gain. PIN terminal for field-deployable sensor nodes. Manufactured under RYD ISO9001 with RoHS compliant materials. Customization available: individual sensitivity calibration certificate, custom acoustic horn/lens coupling, weatherproof housing variant, low-leakage FET for battery IoT, and custom frequency response shaping. Enables fewer-microphone-per-site IoT architectures, reducing deployment cost while maintaining coverage area.
