Overview
The PT-3529WQ is an externally driven piezoelectric buzzer from the PT series by Mallory Sonalert. It operates on a voltage range of 3V to 30V with a nominal rating of 5V. The device produces a dual-tone signal at a frequency of 2.9 kHz, achieving a sound pressure level of 95 dBA. Electrical characteristics include a current draw of 5 mA. Physical dimensions are 42 mm in diameter and 16 mm in height. It utilizes solder pin termination for through-hole mounting.
Feature Summary
- Generates a dual-tone audible alert using external drive circuitry
- Operates across a wide input voltage range from 3V to 30V
- Features a compact cylindrical design suitable for panel integration
Applications
- Industrial equipment status indication
- Alarm signaling systems
- Audible alerts for electronic devices
Procurement Notes
Verify the specific suffix against official Mallory Sonalert documentation to confirm terminal type and acoustic output. Datasheets may list variations such as wire lead or solder pin configurations. Ensure the selected variant matches the required mounting style and electrical interface for the target application design.
Selection Notes
Select this component when a dual-tone indicator is required within a 3V to 30V operating window. The 42mm form factor accommodates standard panel cutouts. Confirm whether solder pins or wire leads are needed based on the assembly process. The 5mA current consumption supports low-power system designs.
Part Context
This part belongs to the PT series of externally driven piezoelectric transducers. These components are distinct from self-oscillating buzzers as they require an external oscillator circuit to generate the audio signal. The series is designed for reliable audible signaling in various industrial and commercial environments.
Replacement Considerations
Cross-reference with PT-3529PQ for identical acoustic specifications but different termination types. Verify that any substitute maintains the 2.9 kHz dual-tone frequency and 95 dBA output level to ensure functional equivalence.
