185PZ10320LFLA

Overview

The DB Products 185PZ10320LFLA is an externally driven piezoelectric transducer designed for acoustic signaling applications. It features a diameter of 10mm and a thickness of 3.2mm, with custom wire leads for integration. The component operates at a resonant frequency of 3.2kHz and delivers a sound pressure level of 80dB when driven by a 10V signal at a distance of 10cm. It supports a maximum voltage of 30VAC and draws a current of 5mA during operation.

Feature Summary

• Externally driven piezoelectric design requiring external circuitry for activation
• Custom wire leads facilitate direct connection to driving circuits
• Compact physical dimensions suitable for space-constrained enclosures

Applications

• Electronic alarm systems
• Audible indicator devices
• Buzzer assemblies in consumer electronics

Procurement Notes

Verify the specific ordering suffix and lead configuration against the manufacturer's latest documentation before procurement. Ensure that the driving circuit provides the required 10V square wave input to achieve the specified acoustic output levels. Confirm mechanical mounting requirements align with the custom wire lead specifications provided in the official datasheet.

Selection Notes

Select this component when an externally driven solution is preferred over integrated active buzzers. Consider the 3.2kHz resonant frequency for optimal audibility in the target environment. Evaluate the 80dB output capability against regulatory noise limits and hearing safety standards for the intended application area.

Part Context

DB Products specializes in acoustic components, including piezo elements and buzzers, serving the global market since 1976. This model belongs to their line of piezoelectric transducers, which are distinct from active buzzers as they require external drive signals. The company focuses on providing customizable acoustic solutions for various industrial and consumer electronic applications.

Replacement Considerations

Consult official substitution lists for compatible piezo elements with matching 10mm diameter and 3.2kHz resonance. Verify that alternative parts support the same 30VAC maximum rating and similar capacitance values to ensure circuit compatibility without redesign.
