PK-12N40PEDGQ

Overview

The PK-12N40PEDGQ is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a continuous tone with a rated voltage of 12 VDC and a supply range of 3 to 15 VDC. The device produces an 83 dBA sound pressure level at a frequency between 3600 Hz and 4600 Hz, drawing 12 mA of current. Designed for through-hole mounting, it features solder pin termination and measures approximately 14 mm in length and 8 mm in width.

Feature Summary

• Piezoelectric technology for reliable acoustic output
• Integrated internal driver circuitry for direct connection
• Through-hole construction with solder pin termination
• Continuous tone operation mode

Applications

• Industrial control panel status indication
• Appliance operational alerts
• Electronic equipment signaling systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance requirements and terminal configuration. Ensure the selected variant matches the required voltage rating and acoustic specifications for the target application environment. Cross-reference the datasheet for precise dimensional tolerances and thermal operating limits before finalizing procurement orders.

Selection Notes

Select this component when a compact, board-mounted audible signal is required for low-voltage DC applications. The through-hole format suits standard PCB assembly processes where surface-mount options are unsuitable. Consider the 83 dBA output level relative to ambient noise conditions and the 12 mA current draw against available power supplies.

Part Context

This part belongs to the PK series of piezoelectric buzzers from Mallory Sonalert. The series offers various voltage ratings and acoustic outputs designed for general-purpose industrial and commercial signaling. The PK-12N40PEDGQ specifically targets applications requiring a moderate sound level with a small footprint.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may differ in acoustic performance or electrical characteristics.
