PT-3529PQ

Overview

The PT-3529PQ is an external drive piezoelectric buzzer from the Mallory Sonalert PT series. It operates on a 5 VDC supply with a current rating of 5 mA. The device produces a dual tone sound at a frequency of 2.9 kHz, achieving a sound pressure level of 95 dBA. It features solder pin termination for through-hole mounting and has physical dimensions of 42 mm in diameter by 16 mm in height.

Feature Summary

• Generates a dual-tone acoustic signal using external drive piezoelectric technology
• Designed for through-hole board mounting via solder pin terminals
• Provides high-intensity audio indication suitable for panel applications

Applications

• Industrial control panels requiring visual and audible status alerts
• Medical equipment indicating operational states or alarms
• Consumer electronics needing compact audio feedback mechanisms

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and terminal configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Check lead times as production cycles may vary based on factory schedules. Ensure voltage ratings match system requirements to prevent component damage.

Selection Notes

Select this model when a low-voltage 5 VDC operation is required for board-mounted indicators. The external drive design allows for flexible waveform generation by the host circuit. Consider the 42 mm diameter for available panel space. The dual-tone feature provides distinct auditory differentiation compared to single-tone alternatives.
