PT-3017L

Overview

The PT-3017L is an externally driven piezoelectric buzzer manufactured by Soberton Inc. It operates at a maximum voltage of 30V and produces a sound pressure level of 95dB. The device resonates at a frequency of 3300Hz and features a circular form factor with a diameter of 30mm. This component requires an external drive circuit for operation, distinguishing it from self-exciting types.

Feature Summary

• Externally driven piezoelectric transducer design
• High acoustic output capability up to 95dB
• Circular housing structure

Applications

• Industrial alarm systems
• Security sirens
• Audible notification devices

Procurement Notes

Verify the requirement for an external drive circuit, as this unit is not self-exciting. Confirm that the 30V maximum rating aligns with the driving signal amplitude. Ensure the 30mm diameter fits the mechanical enclosure constraints. Check lead times, which may extend to nine weeks depending on manufacturer availability.

Selection Notes

Select this model when high volume sound projection is required in a compact circular package. It is suitable for applications where the driver electronics are separate from the transducer. Consider the 3300Hz resonance for optimal efficiency. Evaluate space requirements against the 30mm dimension before finalizing the design.

Part Context

This component belongs to the category of alarms, buzzers, and sirens produced by Soberton Inc. It is part of their line of piezoelectric transducers designed for external drive applications. The product series focuses on reliable audible signaling solutions for various electronic equipment.
