PUI Audio Microphone 2.2 kΩ, 16 kHz Lead Wire

This microphone is a miniature electret sensor designed for integration into electronic and automation systems where Compact sound detection is required. It operates at low voltages and accommodates common connector arrangements for straightforward wiring into control and measurement assemblies. The component is suitable for applications demanding small form‑factor acoustic sensing while complying with environmental material restrictions.

• 0.05 to 16kHz frequency range provides wide‑band audio capture
• 3 to 10V operating window enables low‑voltage system compatibility
• 2.2kΩ impedance facilitates predictable Interface matching
• Lead‑wire connector simplifies installation into assemblies
• RoHS‑compliant materials reduce hazardous‑substance concerns

• Suitable for acoustic monitoring in industrial automation panels
• Ideal for audio input on Compact measurement instruments
• Used for sound detection in electrical safety systems
• Can be used for noise sensing in mechanical condition monitoring

It requires a DC supply between 3V and 10V, typical biasing for electret elements is provided by the host circuitry to polarise the capsule.

Use a bias resistor and coupling capacitor arrangement suited to a 2.2kΩ source impedance to ensure compatible input loading and DC blocking to downstream amplifiers.

The sensor has a very small footprint with a low profile height of 5mm which permits placement in shallow cavities or behind panels with limited clearance.

The materials meet RoHS requirements, so standard lead‑free assembly and handling procedures apply during manufacturing and installation.
