Overview
The PS-733EWDGQ is an internally driven piezo indicator buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 5 to 15 volts with a current consumption of 200mA. The device produces a sound pressure level of 85dB at 12V measured at 300cm. Its acoustic frequency ranges from 2.5kHz to 4.5kHz. The unit features surface mount wire leads and has physical dimensions of 32x46x1 mm.
Feature Summary
- Internally driven piezo technology for simplified circuit integration
- Surface mount configuration utilizing wire leads for assembly
- Wide operating voltage compatibility within the specified DC range
Applications
- Industrial equipment status indication
- Medical device alert systems
- Consumer electronics notification signals
Procurement Notes
Verify the specific voltage rating and lead configuration against your schematic requirements. Confirm that the surface mount wire lead style matches your PCB layout or harness design. Ensure the acoustic output meets the necessary audibility standards for the intended application environment. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when an internally driven solution is required to reduce external driver complexity. Consider the surface mount wire lead format if through-hole mounting is not feasible but rigid board mounting is preferred over standard SMD packages. Evaluate the 85dB output level against the ambient noise conditions of the installation site to ensure adequate alerting capability.
Part Context
This model belongs to the Mallory Sonalert product line, which specializes in audio indicators and alarms. The company provides solutions for industrial, medical, and consumer sectors. The PS-733EWDGQ represents their piezo-based internal drive technology, designed for reliable acoustic signaling in various electronic assemblies without requiring complex external driving circuits.
Replacement Considerations
Consult official Mallory Sonalert documentation for direct cross-references. Verify mechanical footprint and electrical characteristics before substituting with other piezo buzzers.
