PS-733WDR-SQ

Overview

The PS-733WDR-SQ is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for industrial audio indication. It features an internally driven circuit requiring only DC input, eliminating the need for external oscillators. The device operates within a voltage range of 5 to 15V and produces a sound pressure level of 95dB. It generates tones in the frequency range of 2.5kHz to 4.5kHz. The unit utilizes a flange-style mounting configuration with dimensions of approximately 32mm x 46mm x 16mm.

Feature Summary

• Internally driven piezoelectric technology for simplified integration
• Flange-style mechanical mounting for secure panel installation
• Wide operating voltage compatibility for flexible power supply design

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Automotive diagnostic signaling

Procurement Notes
