PUI Audio Microphone MEMS, 18 kHz

This microphone is a Compact MEMS transducer designed for general voice pick-up and integration into electronic systems. It operates across a wide audible bandwidth and is suitable for low-voltage environments where an omnidirectional response is required. The device is supplied without a cable and connects via a pin-type interface, making it appropriate for board-level or module integration in automation and electrical projects.

• Omni-directional pick-up ensures uniform sound capture around the element
• Frequency response spans 0.02 kHz to 18 kHz for broad audio coverage
• Sensitivity of -26 dB delivers clear voice-level signal strength
• Operates from 1.5V to 3.6V for low-voltage system compatibility
• Pin-type connector enables straightforward board mounting
• Compliance with REACH and RoHS supports regulatory needs

• Suitable for voice-activated control in industrial automation
• Ideal for acoustic sensing in electronics prototypes
• Used for hands-free audio capture in electrical panels
• Can be used for environmental noise monitoring in mechanical settings

It functions across a 1.5V to 3.6V range, allowing use with low-voltage sensors and microcontroller supplies.

The element covers down to 0.02 kHz and up to 18 kHz, providing adequate response for both low-frequency speech content and higher-frequency harmonics.

A pin-type connector is used, intended for direct connection to sockets or PCB headers without an attached cable.

The transducer is a Compact 4mm device, designed for tight-space installations and module-level placement.
