PK-35N29PQ

Overview

The PK-35N29PQ is an external drive piezoelectric buzzer from the Mallory Sonalert PT series. It operates on a voltage range of 3 to 28 VDC with a rated frequency of 2.9 kHz. The device produces a continuous tone with a sound pressure level between 85 and 102 dBA. It features solder pin termination for through-hole mounting and has physical dimensions of 42 mm in diameter by 15 mm in height.

Feature Summary

• External drive piezoelectric technology
• Continuous tone output
• Through-hole solder pin installation

Applications

• Industrial equipment status indication
• Control panel audio alerts
• General purpose alarm signaling

Procurement Notes

Verify the specific sound pressure level requirement, as specifications indicate a range of 85 to 102 dBA. Confirm that the external drive circuitry matches the component's requirements. Ensure the 42 mm mounting footprint and 15 mm height are compatible with the target enclosure design before finalizing procurement.

Selection Notes

Select this component when a high-intensity audible alert is required for industrial environments. The wide operating voltage range allows flexibility in power supply design. Consider the external drive requirement if integrated oscillator solutions are not preferred or available within the system architecture constraints.

Part Context

This part belongs to the Mallory Sonalert PT series of piezoelectric buzzers. These components are designed for robust performance in demanding applications. The series typically offers various voltage ratings and acoustic outputs to suit different industrial signaling needs.

Replacement Considerations
