PUI Audio Microphone MEMS, 20 kHz

This miniature microphone is a MEMS-based sensing element designed for audio capture and acoustic measurement in industrial and electronic systems. It operates across a wide frequency range and is suitable for integration where compact, low-voltage sound detection is required. The component offers an omnidirectional pickup characteristic and a pin-type electrical Interface for straightforward connection in sensor and instrumentation assemblies.

• Omnidirectional polar pattern for uniform sound detection
• 300Ω impedance for predictable matching with preamplifiers
• Sensitivity -42dB to detect low-level acoustic signals
• High SPL 160dB capability for loud-source measurement
• Operates from 1.5V to 3.6V for low-voltage systems

• Suitable for acoustic sensors in automation equipment
• Ideal for sound-level monitoring in mechanical testing
• Used for audio input in embedded electronics designs
• Can be used for environmental noise logging in facilities

It uses a pin-type connector that allows direct mating to PCB headers or harnesses in Compact assemblies.

The Active element measures 2.75mm in length, permitting installation where a minimal profile is required.

The device responds from 0.02 kHz up to 20 kHz, covering infrasonic through full audible bandwidth for diagnostic and monitoring tasks.

The component meets REACH and RoHS standards, indicating conformity with common substance‑restriction requirements in electronics manufacturing.
