PUI Audio Microphone MEMS, 20 kHz

This microphone is a Compact MEMS sensor designed for capturing sound across a broad audible range in embedded and instrumentation contexts. It operates at low supply voltages and is suited to electronic systems where small form factor and wide frequency coverage are required. The device connects via a pin-style Interface and is built to meet contemporary material restrictions for industrial use.

• Omni-directional pick-up providing uniform coverage for multi-source capture
• 300Ω impedance enabling predictable interfacing with preamps
• -42 dB sensitivity for Detectable signal levels in controlled environments
• 20 kHz frequency response preserving high-frequency content up to the audible limit
• 160 dB maximum SPL allowing recording of very loud sound events
• Operates from 1.5 to 3.6V for compatibility with low-voltage designs

• Suitable for voice acquisition in automation control panels
• Ideal for acoustic monitoring in mechanical test rigs
• Used for on-board audio sensing in Compact embedded systems
• Can be used for high-SPL measurement tasks in industrial diagnostics

It employs a pin-type termination intended for soldering or through-hole retention on a PCB.

The construction conforms to RoHS and REACH material restrictions limiting certain hazardous chemicals.

The sensor’s supply range tops out at 3.6V while remaining functional down to 1.5 V.

Its maximum sound pressure level rating is 160 dB, suitable for capturing high-intensity acoustic transients.

No cable is supplied, the unit is provided without an attached lead.
