PUI Audio Microphone MEMS, 20 kHz

This omnidirectional MEMS microphone is designed for low-voltage digital audio capture in industrial and electronic systems. It converts acoustic signals into an I2S output suitable for integration with digital processors and control units, offering broad frequency coverage for voice and environmental sensing in automation and machine‑interface contexts.

• Omnidirectional pickup for uniform sound capture across angles
• Frequency response of 0.02 to 20 kHz for wideband audio detection
• Sensitivity -26 dB enabling detection of low‑level signals
• Operates from 1.5V to 3.6V for low‑voltage system compatibility
• Pin‑type connector for straightforward board‑level connection
• REACH and RoHS conformity supporting regulatory material limits

• Suitable for voice detection in machinery safety systems
• Ideal for acoustic monitoring in environmental control units
• Used with embedded controllers for hands‑free interfaces
• Can be used for sound‑based diagnostics in electromechanical equipment

It accepts a supply between 1.5V and 3.6 V, allowing use with common low‑voltage logic rails and battery‑powered electronics.

The device responds from 0.02 kHz up to 20 kHz, covering subsonic monitoring through the full audible range for voice and machine‑noise analysis.

It employs a pin‑type connector, compatible with soldering or pin‑header mounting on PCB layouts.

The microphone meets REACH and RoHS requirements, indicating it conforms to the specified substance restrictions.
