PL-35N29WQ

Overview

The PL-35N29WQ is an industrial-grade piezoelectric buzzer from the Mallory Sonalert PL series. It operates on a DC slow pulse tone at a frequency of 2.9 kHz. The device supports a voltage range of 3 to 24 VDC and draws a current of 10 mA. It produces a sound pressure level of 95 dBA. The unit features wire lead termination for flush mounting. Its physical dimensions are 42 mm in diameter and 16 mm in height.

Feature Summary

• Generates a slow pulse audio tone for industrial alerting
• Utilizes internal piezoelectric technology for reliable operation
• Designed for flush panel mounting applications

Applications

• Industrial machinery status indication
• Equipment fault signaling
• Control panel alarm systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm electrical characteristics and terminal type. Ensure the input power supply matches the 3-24 VDC requirement. Confirm that the 42 mm mounting hole dimension aligns with the enclosure design before procurement.

Selection Notes

Select this component when a high-decibel, low-current indicator is required for panel-mounted installations. The slow pulse characteristic distinguishes it from continuous tone alarms. Verify compatibility with the available control voltage within the specified operating range.

Part Context

This part belongs to the PL series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series is known for robust construction suitable for demanding environments. The PL designation indicates a specific form factor and mounting style within the company's broader audio indicator portfolio.

Replacement Considerations

Consult official substitution guides for equivalent models. Cross-referencing requires matching voltage, frequency, and mounting dimensions.
