AW-05CR-NC

Overview

The AW-05CR-NC is an internally driven piezo buzzer manufactured by PUI Audio, Inc. It operates on a rated DC voltage of 24 V with a functional range of 10 to 28 V. The device draws between 9 and 35 mA and produces a sound pressure level of 87 dB at 24 V measured from a distance of 100 cm. It features multiple frequency output capabilities and utilizes active driver circuitry. The unit is designed for base mounting and has a diameter of 113 mm (4.449 inches) with a maximum seated height of 27.50 mm (1.083 inches).

Feature Summary

• Internally driven active piezo technology eliminates the need for external oscillator circuits.
• Base mount configuration allows for secure installation in various enclosures.
• Operates within a wide voltage range of 10 to 28 VDC for flexible power integration.

Applications

• Industrial alarm systems requiring audible alerts.
• Commercial equipment status indicators.
• Home appliance audio signaling.

Procurement Notes

Verify the specific suffix codes against official PUI Audio documentation to ensure correct voltage and acoustic specifications. Confirm that the base mount style matches your enclosure design requirements. Check operating temperature ratings (-25°C to +70°C) against your environmental conditions. Ensure input voltage stays within the 10-28V range to prevent damage or malfunction.

Selection Notes

Select this component when an active, self-oscillating sound source is required without complex driving electronics. The 24V rating suits standard industrial control panels. Consider the 113mm diameter for available panel space. The 87dB SPL provides adequate audibility for general industrial environments but may require higher output models for noisy settings.

Part Context

This part belongs to the PUI Audio AW series of industrial buzzers and audio indicators. The series offers various voltages, frequencies, and mounting styles. The AW-05CR-NC specifically denotes a 24V piezo unit with base mounting and internal drive circuitry, distinct from flange-mounted or lower-voltage variants in the same product line.

Replacement Considerations

Direct substitutes must match the 24V rating, 113mm diameter, and base mount style. Verify that any replacement maintains the 87dB SPL and active driver requirement. Cross-reference with PUI Audio's current availability list as older series parts may have discontinued equivalents.
