PT-2038WQ

Overview

The PT-2038WQ is a piezoelectric alarm indicator manufactured by Mallory Sonalert Products Inc. It operates on a rated voltage of 5VDC and features a single-tone continuous sound output. The device utilizes panel mount installation with a flange design and has a round shape. Key electrical characteristics include a peak-to-peak signal specification suitable for standard logic interfaces.

Feature Summary

• Piezoelectric transducer technology for reliable acoustic signaling
• Single-tone continuous audio output for clear status indication
• Panel mount configuration with integrated flange for secure enclosure integration

Applications

• Industrial and commercial alarm systems
• Security system status indicators
• Emergency notification devices

Procurement Notes

Verify the specific datasheet revision to confirm exact acoustic pressure levels and current consumption parameters, as these values are critical for power budget calculations. Ensure the mounting hole dimensions match the target enclosure design. Confirm RoHS compliance status if required for your specific regulatory environment before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 5VDC audible alert is required for panel-mounted applications. The single-tone output is suitable for simple on/off status indications rather than complex warning patterns. Consider the physical size and flange mounting style against available panel space constraints during the mechanical design phase.

Part Context

This part belongs to the Mallory Sonalert product line, which specializes in audible and visual warning devices. The brand is recognized for providing solutions across industrial, consumer, transportation, medical, and military markets. The PT-2038WQ represents their standard piezoelectric alarm category designed for general-purpose indication tasks.

Replacement Considerations

Mallory Sonalert maintains cross-reference sheets for obsolete components from other manufacturers, such as Murata buzzers. Consult official Mallory documentation to identify verified substitute part numbers that maintain equivalent electrical and mechanical specifications.
