PLD-35A29WQ

Overview

The PLD-35A29WQ is an internally driven piezoelectric buzzer from the Mallory Sonalert PL series. It operates on a 12 VDC supply with a current rating of 10 mA. The device produces a slow pulse tone at a frequency of 2.9 kHz with a sound pressure level of 95 dB. It features wire leads for connection and is designed for flush panel mounting. The physical dimensions are 42 mm in diameter and 16 mm in height.

Feature Summary

• Internally driven piezoelectric design eliminates need for external oscillators
• Slow pulse audio output pattern for distinct alerting
• Flush mount configuration with flange installation style
• Wire lead termination for direct circuit integration

Applications

• Industrial equipment status indication
• Control panel alarm signaling
• Medical device auditory alerts
• Transportation system warnings

Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and acoustic specifications match the design requirements. Confirm RoHS3 compliance status if environmental regulations apply to the target assembly. Check manufacturer documentation for any recent product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when a self-contained, high-decibel audible indicator is required for 12 VDC systems. The internal drive circuit simplifies PCB layout by removing external driver components. Ensure the mounting hole size accommodates the 42 mm diameter and that the enclosure allows for proper sound projection from the top port.
