Overview

The PT-2045FWQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 3 to 28 VDC and produces a continuous tone at a frequency of 4.5 kHz. The device delivers a sound pressure level of 85 dBA. It features a 24 mm flange design intended for panel mounting applications.

Feature Summary

Piezoelectric transducer technology
Continuous tone output
Panel mount installation via 24 mm flange

Applications

Industrial audio indicators
Control panel alarms
Equipment status alerts

Procurement Notes

Verify the specific operating voltage requirements against the 3-28 VDC specification before procurement. Confirm that the 24 mm flange dimension matches the panel cutout. Ensure the 85 dBA acoustic output meets the environmental noise requirements of the installation site. Check for RoHS compliance documentation if required by project specifications.

Selection Notes

Select this component when a compact, low-voltage DC piezo buzzer is required for panel-mounted applications. The 24 mm flange provides secure mechanical attachment. Consider the 4.5 kHz frequency and 85 dBA volume for audible alerting in moderate noise environments. Verify compatibility with the system's power supply voltage range.
