PK-27H36EPSQ

Overview

The PK-27H36EPSQ is a piezoelectric buzzer indicator manufactured by Mallory Sonalert. It operates on a DC voltage range of 3 to 24 volts with a rated voltage of 12 VDC and a current consumption of 18 mA. The device produces a constant tone at a frequency of 3500 Hz (3.5 kHz) with a sound pressure level between 80 and 102 dB. It features through-hole termination for PCB mounting and has physical dimensions of 30 mm in diameter and 16 mm in height.

Feature Summary

• Generates a continuous acoustic signal using piezoelectric technology
• Supports wide input voltage operation from 3 to 24 volts DC
• Designed for direct printed circuit board installation via through-hole pins

Applications

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

Procurement Notes

Verify the specific sound pressure level requirement, as specifications indicate a range of 80 to 102 dB. Confirm that the 3 to 24 volt DC operating range aligns with the system power supply. Ensure the through-hole mounting style and 30 mm diameter fit the designated PCB layout and enclosure constraints before ordering.

Selection Notes

Select this component when a compact, board-mounted audible indicator is required for low-voltage DC systems. It is suitable for applications needing a steady tone rather than pulsed signals. Consider the dimensional constraints of the 30 mm x 16 mm package and the need for through-hole assembly processes during design integration.

Part Context

This part belongs to the Mallory Sonalert line of audio indicators and buzzers. It is categorized under board-mount devices designed for integration into electronic assemblies. The product serves as an auditory feedback mechanism within larger electrical systems, distinguishing itself from panel-mount or industrial-grade variants through its smaller form factor and direct PCB attachment method.

Replacement Considerations

No public substitute part numbers are documented.
