PT-2725PQ

Overview

The PT-2725PQ is a piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates at a frequency of 2.5 kHz with an external drive requirement. The device features a 30 mm diameter and 12 mm height, utilizing through-hole solder pin termination. Rated for 5V to 30V peak-to-peak input, it delivers a sound pressure level of 90 dB.

Feature Summary

• Externally driven piezoelectric design
• Through-hole mounting configuration
• Dual-tone audio output capability

Applications

• Industrial control panels
• Electronic equipment alarms
• Audio indicator systems

Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm exact electrical characteristics and acoustic properties. Ensure compatibility with external driving circuits regarding voltage and frequency requirements before procurement.

Selection Notes

Select this component for applications requiring a compact, externally driven piezo transducer. Confirm that the system provides the necessary AC signal for operation, as this unit lacks internal oscillation circuitry. Validate mechanical fit within the 30 mm diameter constraint.

Part Context

This part belongs to the PT series of piezoelectric buzzers from Mallory Sonalert. These components are designed for integration into larger electronic assemblies where the driving signal is generated by external logic or microcontrollers rather than internal oscillator circuits.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may not match the specific 2.5 kHz frequency or 90 dB acoustic output without detailed electrical testing.
