PT-2726FWQ

Overview

The PT-2726FWQ is a piezoelectric transducer manufactured by Mallory Sonalert Products Inc. It operates at a frequency of 2.6 kHz with a sound pressure level of 90 dB. The device is designed for external driving and requires a 12 VDC supply, drawing 8 mA of current. Physical dimensions are 30 mm in length and 10 mm in diameter. It utilizes a three-wire configuration for connectivity.

Feature Summary

• Piezoelectric construction for reliable acoustic output
• Externally driven transducer design requiring external circuitry
• Three-wire interface for simplified integration

Applications

• Industrial equipment status indication
• Consumer electronics audible alerts
• Transportation system signaling

Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and acoustic specifications. Confirm that the externally driven nature aligns with the host controller capabilities. Check RoHS compliance documentation for regulatory requirements. Ensure mechanical mounting constraints accommodate the cylindrical form factor. Validate electrical parameters against the official datasheet before finalizing procurement.

Selection Notes

Select this component when an externally driven piezoelectric source is required rather than a self-oscillating buzzer. The 12 VDC rating suits standard low-voltage industrial control systems. Consider the 90 dB output sufficient for moderate noise environments. Evaluate the three-wire connection method against available PCB or wiring space. Compare physical dimensions against enclosure constraints during the design phase.
