PLD-27A35WQ

Overview

The PLD-27A35WQ is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert. It operates on a 12 VDC nominal voltage with a current rating of 15 mA and draws power within a 3-24VDC range. The device produces a slow pulse tone at a frequency of 3.5 kHz with a sound pressure level of 95 dBA. It features wire lead termination and flange mount installation. The physical dimensions are 30 mm in diameter and 16 mm in height, belonging to the PL series.

Feature Summary

• Generates audible alerts using piezoelectric technology for reliable industrial signaling
• Produces a slow pulse audio pattern to indicate specific operational states
• Designed for direct panel integration via flange mounting style
• Operates on standard low-voltage DC power supplies

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection systems
• Process monitoring audio alerts

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to confirm electrical characteristics and acoustic output specifications. Ensure the selected variant matches the required voltage range and mounting configuration for the target enclosure. Cross-reference the component number with authorized distributors to confirm availability and compliance with current environmental regulations such as RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when a high-decibel slow pulse alert is required for panel-mounted applications. The 15 mA current draw suits low-power control circuits, while the 95 dBA output ensures audibility in noisy environments. Verify that the 30 mm mounting hole dimension aligns with the existing chassis design. Confirm that the wire lead termination method is compatible with the system's wiring harness or PCB interface requirements.

Part Context

This part belongs to the PL series of industrial audio indicators from Mallory Sonalert. The series specializes in piezoelectric buzzers designed for robust performance in demanding environments. These components typically feature self-drive capabilities and are engineered for long-term reliability in continuous operation scenarios common in manufacturing and automation sectors.

Replacement Considerations

Consult the Mallory Sonalert product cross-reference guide for verified substitutes. Ensure any replacement maintains identical voltage ratings, sound pressure levels, and mounting dimensions to preserve system functionality without requiring mechanical redesign.
