PUI Audio Microphone ECM, 16 kHz

This microphone is a Compact electret condenser transducer designed for general-purpose sound capture in industrial and electronic systems. It operates at low supply voltages and is intended for integration where small size and omnidirectional pickup are required, such as embedded audio sensing or voice detection in automation and control equipment.

• Omnidirectional pickup for uniform sound capture in confined spaces
• Sensitivity of -35dB to detect low-level acoustic signals
• Frequency response from 0.05 to 16kHz for wideband audio reproduction
• Operates on 2 to 10V to suit low-voltage systems
• High impedance 2200Ω for compatibility with high-impedance inputs
• Pin-type connector for straightforward board or socket mounting

• Suitable for voice activity detection in automation controllers
• Ideal for acoustic monitoring in electrical enclosure systems
• Used with analogue front-ends in electronics test rigs
• Can be used for noise sensing in mechanical fault detection

It uses a pin-type electrical Interface intended for direct connection to sockets or PCB headers.

The 2200Ω impedance typically requires a high-impedance input stage or appropriate impedance matching to maintain signal level.

It meets REACH and RoHS standards restricting hazardous substances in components.

Yes, its 2 to 10V operating range allows operation from common low-voltage battery supplies.
