PK-26N04W-24VQ

Overview

The PK-26N04W-24VQ is an electromechanical audio indicator manufactured by Mallory Sonalert. It operates on a 20-28 VDC supply with a rated voltage of 24 VDC and draws 25 mA. The device produces a continuous tone at a frequency of 400 Hz with a sound pressure level of 98 dBA. Its physical dimensions are 26 mm in diameter and 15 mm in height, featuring wire lead termination and flange mount installation.

Feature Summary

• Electromechanical construction for reliable acoustic output
• Continuous tone generation capability
• Flange mount design for secure panel attachment

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Equipment fault detection alerts

Procurement Notes

Verify the specific suffix codes against official Mallory Sonalert documentation to ensure correct voltage and mounting configurations. Confirm that the wire lead type matches the intended circuit connection requirements. Check for any recent product change notifications or revision updates that may affect compatibility with existing designs.

Selection Notes

Select this component when a low-frequency continuous audible alert is required for industrial environments. Ensure the operating voltage range of 20-28 VDC aligns with the system power supply. Consider the 98 dBA output level for adequate audibility in noisy settings compared to lower decibel alternatives.

Part Context

This part belongs to the Mallory Sonalert series of industrial audio indicators. It is designed for robust performance in demanding applications requiring clear visual and auditory feedback. The electromechanical nature distinguishes it from piezoelectric counterparts in terms of sound profile and drive requirements.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Cross-reference electrical parameters such as voltage, current, and frequency before considering alternative models.
