PK-12N40PEQ

Overview

The PK-12N40PEQ is a piezoelectric buzzer from Mallory Sonalert Products Inc. It operates on a constant voltage of 3 to 15 VDC with a frequency of 4.1 kHz. The device features an 82 dB SPL rating and draws 10 mA current at its 12 VDC rated voltage. Dimensions are 14 mm x 8 mm, with a height of 7.5 mm and a diameter of 13.8 mm. It utilizes through-hole solder pin termination and functions within a temperature range of -20°C to +70°C.

Feature Summary

• Piezoelectric technology for reliable acoustic signaling
• Sealed construction for environmental protection
• Through-hole mounting for board integration

Applications

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

Procurement Notes

Verify the specific suffix 'EQ' against official Mallory Sonalert documentation to confirm exact sealing or terminal specifications. Ensure the operating voltage range aligns with system requirements. Confirm RoHS compliance status via the manufacturer datasheet before procurement.

Selection Notes

Select this component for applications requiring a compact, sealed piezoelectric indicator. The 4.1 kHz frequency provides distinct audibility. Verify that the 10 mA current draw fits the power budget. Ensure the 14x8mm form factor fits the PCB layout constraints.

Part Context

This part belongs to the PK series of board-mount buzzers. It shares the 4.1 kHz frequency characteristic with other variants like the PK-12N40PQ but differs in physical dimensions and sealing details. The series is designed for general-purpose audio indication in electronic assemblies.

Replacement Considerations

The PK-12N40PQ is a related variant with similar electrical characteristics but different physical dimensions (14x8mm vs 13.8mm diameter). Verify mechanical fit and mounting hole alignment when substituting.
