AW-05CW-NC

Overview

The AW-05CW-NC is an internally driven piezo buzzer manufactured by PUI Audio, Inc. It operates at a nominal voltage of 24 V and draws between 8 to 35 mA. The device produces a sound pressure level of 87 dB measured at 24 V from a distance of 100 cm. It features a base mount configuration with a diameter of 113 mm. This component is designed for applications requiring reliable audible signaling without external driver circuitry.

Feature Summary

• Internally driven piezo technology eliminates the need for external oscillators
• Base mount design facilitates secure installation on flat surfaces
• Operates directly on 24 V DC power supply

Applications

• Industrial control panels
• Medical equipment alarms
• Security system indicators

Procurement Notes

Verify that the application environment supports the specified 24 V operating voltage and current draw range. Confirm mechanical compatibility with the 113 mm base mount footprint before integration. Ensure acoustic requirements align with the 87 dB output specification at the intended measurement distance. Cross-reference datasheet revisions for any updates to electrical characteristics or mounting dimensions.

Selection Notes

Select this model when an integrated solution is preferred over discrete piezo elements and drivers. It suits designs where space allows for a 113 mm diameter form factor. Consider the 87 dB output sufficient for the target noise environment. Evaluate if the internal drive mechanism meets the required frequency stability compared to externally driven alternatives.
