PLD-27A35PQ

Overview

The PLD-27A35PQ is a piezoelectric buzzer from the Mallory Sonalert PT series, designed for board-mount applications. It operates on a DC voltage range of 3 to 24VDC with a rated voltage of 12V and a current draw of 10mA. The device produces a dual-tone signal at a frequency of 3.5kHz with a sound pressure level of 95dBA. It features solder pin termination and through-hole mounting. Physical dimensions are 30mm in diameter and 16mm in height.

Feature Summary

• Generates a dual-tone acoustic signal using piezoelectric technology
• Supports constant or slow pulse operation modes
• Utilizes solder pin termination for direct board integration

Applications

• Industrial control panel audio indicators
• Embedded system status alerts
• Equipment fault signaling

Procurement Notes

Verify the specific operating mode configuration required for the application, as the part supports both constant and slow pulse functions. Confirm that the 3-24VDC input range aligns with the target circuit design. Ensure mechanical clearance accommodates the 30mm diameter and 16mm height specifications during PCB layout planning.

Selection Notes

Select this component when a high-decibel dual-tone alert is necessary for board-mounted systems. The wide voltage tolerance allows flexibility in power supply design. Consider the physical size constraints relative to other PT series variants if space is limited.

Part Context

This component belongs to the Mallory Sonalert PT series of piezoelectric transducers. The series is characterized by robust construction and reliable acoustic performance for industrial and commercial audio indication needs.

Replacement Considerations

Cross-reference with PT-2735FPQ for similar electrical characteristics but verify mounting style differences.
