PT-1250PQ

Overview

The PT-1250PQ is an external drive piezoelectric buzzer from the Mallory Sonalert PT series. It operates on a 5 VDC supply with a current rating of 1.5 mA. The device produces a dual tone signal at a frequency of 4.8 kHz with a sound pressure level of 80 dBA. Designed for through-hole mounting, it features solder pin termination and measures 13.8 mm in diameter by 4 mm in height.

Feature Summary

• Generates a dual-tone acoustic signal using external drive piezoelectric technology
• Supports through-hole installation via solder pin terminations
• Provides high-intensity audio indication suitable for panel integration

Applications

• Electronic equipment status indication
• Control panel alarm signaling
• Industrial machinery operational alerts

Procurement Notes

Verify the specific voltage and current requirements against the system design before procurement. Confirm that the through-hole footprint matches the PCB layout. Ensure the operating environment accommodates the specified acoustic output levels. Check for any regional compliance certifications required for the target market.

Selection Notes

Select this component when a compact, low-power audible indicator is needed. The 5 VDC rating suits standard logic-level circuits. The dual-tone feature offers distinct auditory differentiation compared to single-tone devices. Consider the 13.8 mm diameter for spatial constraints within the enclosure design.

Part Context

This part belongs to the PT series of transducers manufactured by Mallory Sonalert. The series focuses on board-mount audio indicators designed for reliable performance in various electronic applications. The PT designation indicates a specific form factor and mounting style within the manufacturer's broader audio product portfolio.

Replacement Considerations

Consult official Mallory Sonalert documentation for verified substitute part numbers. Ensure any replacement maintains compatible voltage, current, and acoustic specifications.
