Overview
The PS-733EWDYQ is an internally driven piezoelectric buzzer from the Mallory Sonalert industrial series. It operates on a DC voltage range of 5 to 15 volts and delivers a sound pressure level of 95 dB at 12V. The device features a frequency sweep (FS) function with an oscillation range of 2.5 kHz to 4.5 kHz. Physical dimensions are 32 mm x 46 mm x 18 mm, utilizing wire leads for termination and surface mount installation.
Feature Summary
- Internally driven piezoelectric design for simplified integration
- Frequency sweep audio output for enhanced alert audibility
- Industrial-grade construction suitable for demanding environments
Applications
- Industrial machinery status indication
- Medical equipment alarm systems
- Transportation vehicle warning signals
- Consumer appliance fault alerts
Procurement Notes
Verify that the specific part number matches the required frequency sweep characteristics and physical mounting constraints. Confirm that the operating voltage range aligns with the system power supply. Ensure the wire lead termination type is compatible with the target PCB or harness interface before finalizing procurement orders.
Selection Notes
Select this component when an audible sweep tone is required rather than a continuous beep. Consider the 95 dB output level against ambient noise requirements. Evaluate the 32x46x18 mm footprint against available panel space. Verify that the internal driver capability meets the current draw specifications of the host circuit design.
Part Context
This buzzer belongs to the Mallory Sonalert industrial alarm category, known for reliable acoustic signaling in critical applications. The brand has over a century of experience in electronic sound solutions, establishing standards for panel alarms and indicators across medical, transportation, and industrial sectors globally.
Replacement Considerations
No public confirmed substitute part numbers are documented for this specific model. Cross-referencing requires matching the 5-15VDC input, 95dB output, and frequency sweep functionality precisely.
