PT-3110P-05Q

Overview

The PT-3110P-05Q is an external drive piezoelectric buzzer manufactured by Mallory Sonalert. It operates on a 5 VDC rated voltage with a current consumption of 2 mA. The device produces a dual tone sound at a frequency of 1.1 kHz, achieving a sound pressure level of 90 dBA. It features solder pin termination and through-hole mounting style. The physical dimensions are 34.5 mm in diameter and 10.3 mm in height.

Feature Summary

• Generates a dual-tone acoustic signal using piezoelectric technology
• Designed for external drive applications requiring low current consumption
• Constructed for reliable through-hole PCB integration

Applications

• Electronic equipment status indication
• Audible alerts for control panels
• General purpose audio signaling in consumer devices

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required drive circuits and acoustic specifications. Confirm that the external drive configuration matches the system design, as this component does not contain internal oscillators. Check RoHS compliance documentation for regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a distinct dual-tone alert is required with minimal power draw. Ensure the driving circuit can supply the necessary voltage and current without exceeding the 2 mA rating. Consider the 34.5 mm diameter footprint for enclosure space constraints compared to smaller electromagnetic alternatives.

Part Context

This part belongs to the PB series of audio indicators from Mallory Sonalert. It represents the piezoelectric category within their lineup, distinguished from electromagnetic buzzers by its lower current usage and different acoustic characteristics. The series offers various voltage and frequency options for diverse signaling needs.
