PK-41N29W-24VQ

Overview

The PK-41N29W-24VQ is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. Designed for industrial applications, this electromechanical audio indicator operates on a continuous tone at a frequency of 2900 Hz. It accepts a DC voltage input range of 12 to 28 volts and draws a current of 20 mA. The device produces a sound pressure level between 87 and 104 dB(A) when powered at 24 VDC. Physically, the unit measures 44 mm in diameter by 14 mm in length and utilizes through-hole wire leads for mounting.

Feature Summary

• Internally driven piezoelectric design eliminates the need for external oscillators
• Continuous tone operation provides consistent audible alerting
• Wide DC voltage acceptance range supports flexible power supply integration

Applications

• Industrial machinery status indication
• Factory automation control panels
• Equipment fault alarm systems

Procurement Notes

Verify that the operating environment remains within the specified electrical limits to ensure longevity. Confirm mechanical clearance for the 44 mm diameter housing before installation. Ensure wiring connections are secure to maintain signal integrity during continuous operation.

Selection Notes

Select this component when a self-contained, high-decibel audible alert is required without complex driver circuitry. The wide voltage tolerance simplifies power distribution in varied industrial settings. Consider the physical dimensions and through-hole mounting style for panel compatibility.
