Overview
The PT-2745WQ is an externally driven piezoelectric transducer from the Mallory Sonalert series. It operates at a resonant frequency of 4.5 kHz with a sound pressure level of 90 dB at 5V measured at 10 cm. The device is rated for a maximum operating voltage of 5 VDC and draws a current of 1.5 mA. It features wire lead termination and is designed for panel mount installation using a flange style. The unit has a diameter of 30 mm.
Feature Summary
- Externally driven piezoelectric transducer design
- Panel mount construction with integrated flange
- Wire lead termination for circuit integration
Applications
- Industrial equipment status indication
- Control panel audio alerts
- Electronic device signaling systems
Procurement Notes
Verify the specific electrical requirements against the official datasheet before procurement. Confirm that the driving circuitry can supply the required 1.5 mA current at 5 VDC. Ensure the mounting hole dimensions accommodate the 30 mm diameter flange. Check for RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when an externally driven, high-intensity audible alert is needed for panel-mounted applications. It is suitable for designs requiring a 4.5 kHz tone with minimal power consumption. Consider the flange mounting style for secure installation in enclosures. Compare with other Sonalert series parts if different frequencies or drive types are required.
Part Context
This part belongs to the Mallory Sonalert product line, known for reliable piezoelectric indicators. The PT series typically denotes externally driven transducers. These components are widely used in industrial and commercial electronics where clear, loud audio feedback is necessary for operational status monitoring.
Replacement Considerations
Consult Mallory Sonalert directly for verified substitute part numbers. Cross-referencing should be done based on exact electrical parameters and mechanical dimensions to ensure compatibility.
