PT-2040PQ

Overview

The PT-2040PQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a voltage of 5V and produces a continuous tone at a frequency of 4kHz. Designed for alert and notification applications, this component is part of the PT series. It features through-hole mounting technology with a diameter of 22mm. The device is engineered to deliver reliable audible warnings in various electronic systems requiring compact sound generation solutions.

Feature Summary

• Externally driven piezoelectric design for alert applications
• Compact 22mm form factor suitable for panel integration
• Through-hole termination for secure board mounting

Applications

• Alarm systems
• Buzzer circuits
• Sirens

Procurement Notes

Verify the specific datasheet version for the PT-2040PQ to confirm exact acoustic output levels and electrical tolerances. Ensure compatibility with 5V logic or drive circuits before integration. Cross-reference with official Mallory Sonalert documentation to validate pinout configurations and mechanical dimensions against your enclosure requirements.

Selection Notes

Select the PT-2040PQ when a 5V operating voltage and 4kHz continuous tone are required. Its 22mm size makes it suitable for space-constrained panels. Consider external drive capabilities if variable volume or modulation is needed beyond the basic constant tone specification provided in standard product listings.
