PK-16N04WA-03Q

Overview

The PK-16N04WA-03Q is an industrial electromechanical buzzer from the Mallory Sonalert PK series. It operates on a constant tone at 400 Hz with a rated voltage of 2 to 4 VDC and a current draw of 35 mA. The unit features wire lead termination and flange mount installation. Its physical dimensions are 24 mm x 17 mm x 15 mm, providing a compact form factor for integration into various electronic assemblies requiring audible alerts.

Feature Summary

• Electromechanical construction for reliable acoustic output
• Constant continuous tone generation capability
• Compact flange mount design for secure panel integration

Applications

• Industrial machinery status indication
• Control panel alarm signaling
• Electronic equipment audio alerts

Procurement Notes

Verify that the operating voltage range of 2 to 4 VDC aligns with the target circuit supply. Confirm that the 35 mA current rating is supported by the driving source without exceeding its capacity. Ensure the mounting hole dimensions correspond to the specified 24 mm x 17 mm footprint for proper mechanical fit.

Selection Notes

Select this component when a low-voltage DC power source is available and a specific 400 Hz frequency is required for identification purposes. Consider the wire lead termination style for direct wiring applications. Evaluate the compact 15 mm height against spatial constraints within the enclosure design.

Part Context

This part belongs to the PK series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series is designed for robust performance in demanding environments. The PK-16N04WA-03Q variant specifically targets low-voltage applications, distinguishing it from higher voltage counterparts within the same product family.

Replacement Considerations

PK-16N04WA-12Q: Higher voltage operation (8-16 VDC). PK-16N04WA-24Q: Higher voltage operation (18-24 VDC). Verify voltage compatibility before substitution.
