PS-733WDG-SQ

Overview

The PS-733WDG-SQ is an internally driven piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 5 to 15V and draws approximately 200mA at 12V. The device emits sound at a frequency between 2.5kHz and 4.5kHz with a sound pressure level of 85dB measured at 12V and 300cm. It features surface mount technology with wire leads and includes a green LED indicator. The unit is designed for industrial applications requiring reliable audio signaling.

Feature Summary

• Internally driven piezoelectric design for simplified integration
• Integrated green LED visual indicator
• Surface mount construction with wire leads
• Wide operating voltage range

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment fault signaling
• Process monitoring alerts

Procurement Notes

Verify the specific voltage rating and current consumption requirements against your system design before procurement. Confirm that the surface mount package with wire leads aligns with your PCB layout or assembly process. Ensure the operating temperature range meets your environmental conditions. Cross-reference the manufacturer part number PS-733WDG-SQ with official Mallory Sonalert documentation to confirm availability and lead times through authorized distributors.

Selection Notes

Select this component when an internally driven solution is required to reduce circuit complexity. The integrated LED provides immediate visual feedback alongside the audible alarm. Consider the surface mount form factor if space constraints preclude through-hole mounting. Verify that the 85dB output level is sufficient for the ambient noise environment of the intended application.
