PS-733PRQ

Overview

The Mallory Sonalert PS-733PRQ is a piezoelectric buzzer designed for board-mount applications. It operates on a DC voltage range of 5V to 15V and produces a sound pressure level of 95dB. The device emits an oscillating tone with a frequency between 2.5Hz and 4.5Hz. Its physical dimensions are 32mm x 46mm x 16mm, and it features red coloration.

Feature Summary

• Piezoelectric technology for reliable audio signaling
• Oscillating tone output for distinct alerting
• Board-mount installation style

Applications

• Industrial equipment status indication
• Consumer appliance alarm systems
• Transportation vehicle monitoring

Procurement Notes

Verify the specific operating voltage requirements against the system design, as the component supports a 5V to 15DC range. Confirm that the board-mount form factor aligns with the PCB layout constraints. Ensure the 95dB acoustic output meets the environmental noise requirements for the intended application scenario.

Selection Notes

Select this model when a low-profile board-mount solution is required for audible alerts. The wide input voltage range allows flexibility in power supply design. The oscillating frequency provides a distinct auditory cue compared to continuous tones, suitable for distinguishing critical alarms from standard indicators in mixed-signal environments.
