AT-3045-TF-LW110-R

Overview

The AT-3045-TF-LW110-R is a piezoelectric audio indicator transducer manufactured by PUI Audio. It operates at a resonant frequency of 4.5 kHz with a sound pressure level of 97 dBA. The device is rated for a maximum supply voltage of 50 VDC and draws a maximum operating current of 11 mA. It features wire lead termination and flange mount installation. Physical dimensions include a 30 mm diameter, 5.1 mm depth, and 28 AWG wire leads. The unit functions as an external drive buzzer within an operating temperature range of -30°C to 85°C.

Feature Summary

• Piezoelectric transducer design for high-intensity audible alerts
• Flange mount configuration for secure panel integration
• External drive circuit requirement for operation
• Wire lead termination for flexible wiring connections

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection systems
• Safety warning devices in harsh environments

Procurement Notes

Verify the specific suffix requirements against official PUI Audio documentation before ordering, as variations may exist. Confirm that the external drive circuitry matches the 11 mA current draw and 50 VDC maximum rating. Ensure mechanical clearance accommodates the 30 mm diameter and 5.1 mm depth. Check RoHS compliance status through the manufacturer's latest datasheet or certification documents to meet regulatory standards.

Selection Notes

Select this component when a high-decibel, externally driven piezoelectric buzzer is required for panel mounting. The 4.5 kHz frequency provides distinct audibility in noisy industrial settings. Consider the wire lead option if pre-soldered connections are preferred over pin headers. Evaluate the 97 dBA output against ambient noise levels to ensure adequate alert volume. Verify compatibility with existing control logic driving the external circuit.

Part Context

This part belongs to the PUI Audio AT series of piezoelectric transducers. It is categorized under industrial-grade audio indicators designed for robust performance. The model utilizes a flange mount style, distinguishing it from board-mount alternatives in the same family. It serves as a standalone acoustic element requiring external signal generation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult PUI Audio technical support for direct equivalents or cross-reference with similar 30 mm flange-mount piezo buzzers meeting the 97 dBA and 4.5 kHz specifications.
