PK-26N04W-12VQ

Overview

The PK-26N04W-12VQ is an electromechanical industrial buzzer manufactured by Mallory Sonalert. It operates on a 12 VDC voltage rating with a current consumption of 25 mA. The device produces a continuous tone at a frequency of 400 Hz, achieving a sound pressure level of 98 dBA. Physical dimensions are 26 mm in diameter and 15 mm in height, featuring wire lead termination and flange mount installation style.

Feature Summary

• Electromechanical construction for reliable audio indication
• Continuous tone output optimized for steady-state alerts
• Flange mount design facilitates secure panel integration

Applications

• Industrial machinery status monitoring
• Control panel alarm signaling
• Equipment fault detection systems

Procurement Notes

Verify the specific voltage suffix in the part number to ensure compatibility with the target circuit. Confirm that the 12 VDC requirement aligns with available power supplies. Check mechanical mounting constraints against the specified flange dimensions. Ensure the 98 dBA acoustic output meets regulatory noise requirements for the intended environment.

Selection Notes

Select this component when a moderate volume continuous alert is required for low-voltage DC applications. Consider the electromechanical nature for robust performance in varying temperatures. Evaluate the 400 Hz frequency for distinctiveness against background noise. Compare physical size constraints against available panel space for proper fitment.

Part Context

This model belongs to the PK series of industrial buzzers from Mallory Sonalert. The series is designed for general-purpose audio indication in harsh environments. Variations within the series typically differ by voltage rating, acoustic output, and mounting configuration while maintaining consistent form factors.
