PT-2130PQ

Overview

The PT-2130PQ is an externally driven piezoelectric transducer manufactured by Mallory Sonalert Products Inc. Designed for audible alert applications, this component operates at a nominal voltage of 5V and features a 24mm diameter form factor with through-hole mounting. It is engineered to provide clear audio signals when paired with external drive circuitry, offering adjustable gain and low noise operation suitable for various electronic equipment requiring distinct sound indicators.

Feature Summary

• Externally driven piezoelectric design for flexible integration
• Optimized for low noise operation in alert circuits
• Supports adjustable gain settings via external components

Applications

• Electronic equipment requiring audible alerts
• Industrial control panels
• Consumer electronics signaling systems

Procurement Notes

Verify the specific datasheet version for exact electrical characteristics and mechanical drawings before finalizing designs. Confirm that the external drive circuitry matches the transducer's impedance and voltage requirements. Ensure compliance with relevant safety standards for the intended application environment. Check for any recent product change notices or obsolescence announcements from the manufacturer.

Selection Notes

Select this component when an externally driven solution is preferred over self-oscillating buzzers. The 5V rating suits low-voltage digital logic interfaces. Consider the 24mm size constraint for panel cutouts. Evaluate the need for adjustable gain against fixed-output alternatives. Verify mounting style compatibility with the target enclosure design.
