PT-593SQ

Overview

The PT-593SQ is an external drive piezoelectric transducer from the Mallory Sonalert PT series. It operates within a voltage range of 5 to 150 Vpp and draws 47 mA. The device produces a dual-tone sound at a frequency of 3.5 kHz with a sound pressure level of 90 dBA. It features solder termination and measures 54.5 mm in diameter by 25.5 mm in height.

Feature Summary

• Generates a dual-tone acoustic signal for distinct audio alerts
• Accepts a wide input voltage range from 5 to 150 Vpp
• Designed for surface mount installation via solder termination

Applications

• Industrial machinery status indication
• Equipment fault alarm systems
• Control panel audio signaling

Procurement Notes

Verify the specific drive circuit requirements, as this component requires an external oscillator or driver to function. Confirm that the mounting footprint matches the 54.5 mm diameter specification. Ensure the operating environment supports the specified voltage and current ratings without exceeding thermal limits.

Selection Notes

Select this model when a high-intensity dual-tone alert is required for industrial environments. It is suitable for applications needing a broad voltage tolerance and surface mount compatibility. Compare against single-tone variants if a continuous tone is sufficient for the safety protocol.

Part Context

This component belongs to the PT series of piezoelectric transducers manufactured by Mallory Sonalert Products Inc. These devices are engineered for robust performance in demanding industrial settings. The series offers various acoustic outputs and mounting options to suit different enclosure designs.

Replacement Considerations

Direct substitutes include other Mallory Sonalert PT series models with matching dimensions and electrical characteristics. Verify that any replacement maintains the 3.5 kHz frequency and dual-tone capability to ensure consistent auditory signaling.
