PT-1540PM-P3.5Q

Overview

The PT-1540PM-P3.5Q is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for board-mount applications. It operates on an external drive principle with a voltage range of 5 to 25 VPP. The device generates a dual-tone siren sound at a frequency of 4.0 kHz, achieving a sound pressure level of 85 dB. It features PC pin termination and measures 17 mm by 7 mm.

Feature Summary

Generates a dual-tone siren alert using external drive circuitry
Compact board-mount design suitable for space-constrained assemblies
Operates within a wide voltage range of 5 to 25 VPP

Applications

Industrial control panels requiring audible status alerts
Medical equipment safety warning systems
Transportation vehicle instrumentation audio indicators

Procurement Notes

Verify the specific suffix P3.5Q against your schematic requirements to ensure correct pin configuration and lead length. Confirm that the external drive circuit can supply the necessary peak-to-peak voltage without exceeding component limits. Check RoHS compliance documentation if required for your assembly standards. Ensure the mounting holes align with your PCB layout before finalizing the order.

Selection Notes

Select this component when a high-intensity siren tone is needed in a small form factor. It requires an external oscillator or microcontroller to function, unlike internal drive buzzers. Consider the 85 dB output for environments where moderate noise levels are sufficient. The through-hole PC pins facilitate easy integration into standard printed circuit boards.

Part Context

This part belongs to the PT series of piezoelectric transducers from Mallory Sonalert. The series focuses on compact, board-mount solutions for various audio indication needs. These devices are widely used across industrial, medical, and consumer sectors for reliable acoustic signaling.
