Overview
The PT-2725WQ is an externally driven piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 3 to 28 VDC and draws a current of 1.5 mA at its rated 5 VDC input. The device produces a continuous tone at a frequency of 2.5 kHz with a sound pressure level of 90 dBA measured at 10 cm. Its physical dimensions are 30 mm in diameter and 16 mm in height, featuring wire lead termination for panel mounting via a flange.
Feature Summary
- Externally driven piezoelectric design requiring external oscillator circuitry
- Flange mount configuration for secure panel installation
- Wire lead termination for direct electrical connection
Applications
- Industrial equipment status indicators
- Control panel audio alerts
- General purpose alarm systems
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official part numbering guide to ensure correct acoustic and electrical specifications. Confirm that the application circuit provides the necessary external drive signal, as this component is an externally driven transducer rather than a self-contained buzzer. Cross-reference the datasheet for precise mechanical tolerances and environmental operating limits before finalizing procurement.
Selection Notes
Select this component when an external driver circuit is already present in the system design. Ensure the available drive voltage aligns with the specified 3 to 28 VDC range. Consider the 90 dBA output level relative to ambient noise requirements. Verify that the 30 mm diameter and 16 mm height fit within the designated panel cutout and enclosure space constraints.
Part Context
This part belongs to the PT series of piezoelectric transducers from Mallory Sonalert. These components are designed for integration into custom audio alerting systems where the driving electronics are separate from the acoustic element. The series offers various frequencies and sound pressure levels to suit different industrial and commercial signaling needs.
Replacement Considerations
Consult the Mallory Sonalert PK or PL series datasheets for compatible alternatives. Ensure any substitute matches the 30 mm diameter, 2.5 kHz frequency, and externally driven operational mode.
