PF-35N29WQ

Overview

The PF-35N29WQ is an industrial-grade piezoelectric buzzer from the PL series by Mallory Sonalert. It operates on a DC voltage range of 4 to 28 volts with a nominal rating of 12 VDC. The device emits a fast pulse tone at a frequency of 2.9 kHz and achieves a sound pressure level of 90 dB. Designed for flush mounting, it features wire lead termination and measures 42 mm in diameter by 16 mm in height.

Feature Summary

• Generates a fast pulse acoustic signal suitable for urgent industrial alerts
• Operates within a wide DC voltage range of 4 to 28 volts
• Constructed for durable industrial environments
• Features a compact cylindrical design for panel integration

Applications

• Industrial machinery status indicators
• Factory safety alarm systems
• Equipment fault detection alerts
• Control panel audio signaling

Procurement Notes

Verify the specific operating mode against project requirements, as this model provides a fast pulse output rather than continuous or slow pulse tones. Confirm that the 4-28V DC input range aligns with the available power supply infrastructure. Ensure the enclosure allows for the required 42mm flush mount aperture. Check for any regional distribution restrictions or RoHS compliance documentation prior to finalizing procurement orders.

Selection Notes

Select this component when a high-intensity 90 dB alert is necessary for noisy industrial settings. The wide voltage tolerance simplifies integration across various control voltages. Compare against the SC series if a slower pulse pattern is preferred, or the LSC series if integrated LED indication is required. Ensure the wire lead termination method matches the existing wiring harness specifications.

Part Context

This unit belongs to the PL series of industrial buzzers, which are characterized by robust construction and high acoustic output. The series typically includes variants with different pulse speeds and voltage ratings. The PF-35N29WQ specifically denotes the fast pulse variant within this lineup, distinguishing it from slow pulse models like the PL-35A29WQ.
