PK-12N40PEDYQ

Overview

The PK-12N40PEDYQ is a piezoelectric buzzer from Mallory Sonalert, designed for through-hole mounting. It operates on a DC input with a rated voltage of 12V and a range of 3 to 15V. The device features an internally driven indicator circuit and produces a continuous tone at a frequency of 4.1kHz. Key electrical specifications include a sound pressure level of 83dB and a current rating of 10mA. The unit utilizes solder pin termination and measures 14mm by 8mm.

Feature Summary

• Internally driven piezoelectric technology for simplified integration
• Continuous single-tone audio output capability
• Through-hole solder pin termination for board mounting

Applications

• Electronic equipment status indication
• Industrial control panel alerts
• Consumer appliance signaling

Procurement Notes

Verify the specific suffix 'DYQ' against official Mallory Sonalert documentation to confirm exact packaging or variant details, as suffixes often denote specific handling or reel configurations. Ensure the 12VDC rating aligns with your system's power supply constraints. Cross-reference the 4.1kHz frequency requirement with application acoustic needs before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-current piezoelectric solution is required for board-level assembly. The internal driver eliminates the need for external oscillating circuits, reducing design complexity. Consider the 14x8mm footprint and through-hole requirements during PCB layout planning to ensure mechanical compatibility with the target enclosure or chassis.

Part Context

This part belongs to the PK series of audio indicators from Mallory Sonalert Products Inc., which specializes in piezoelectric and electromechanical alerting devices. The PK series is widely recognized for its reliability in industrial and commercial applications requiring clear visual and audible feedback. This specific model represents a standard constant-tone variant within that product line.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for verified equivalents. Generic replacements may differ in acoustic output or drive requirements.
