Overview
The PT-2725FPQ is a self-drive piezoelectric transducer manufactured by Mallory Sonalert. It operates at a rated voltage of 12 VDC with a current rating of 10 mA. The device produces a dual-tone sound signal at a frequency of 3.5 kHz, achieving a sound pressure level of 88 dBA. It features solder pin termination and through-hole mounting style. The physical dimensions are 30 mm in diameter and 10 mm in height.
Feature Summary
- Self-drive piezoelectric design for direct connection to drive circuits
- Dual-tone acoustic output for distinct auditory signaling
- Through-hole solder pin termination for PCB integration
Applications
- Industrial control panel audio indicators
- Consumer electronics status alerts
- Transportation system warning signals
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Mallory Sonalert or authorized distributors before procurement. Confirm that the 12V DC operating requirement matches the target circuit design. Ensure mechanical clearance allows for the 30mm diameter and 10mm height footprint during PCB layout planning.
Selection Notes
Select this component when a low-profile, board-mounted audible alert is required. The 12V DC rating suits standard logic-level power supplies. The dual-tone feature provides higher attention-grabbing capability compared to single-tone devices. Verify that the 88 dBA output meets the ambient noise requirements of the installation environment.
Part Context
This part belongs to the PT series of piezoelectric buzzers from Mallory Sonalert. The series focuses on compact, through-hole mounted audio indicators suitable for space-constrained applications. The manufacturer specializes in industrial and medical alarm systems, establishing this component as a standard solution for reliable acoustic signaling.
Replacement Considerations
Cross-reference with other Mallory Sonalert PT-series variants for different voltage ratings or tone configurations. Verify mechanical compatibility if substituting with third-party piezo buzzers, ensuring identical pin spacing and mounting hole dimensions.
