PT-2207

Overview

The PT-2207 is an externally driven piezoelectric transducer manufactured by Soberton Inc. It operates at a nominal voltage of 10V with a current consumption of 3mA. The device produces a sound pressure level of 85dB at 10V and resonates at a frequency of 4kHz. It features a 22mm diameter and utilizes through-hole PC pin termination for mounting.

Feature Summary

• Externally driven piezoelectric design requiring external drive circuitry
• Non-washable construction suitable for specific assembly environments
• Through-hole PC pin termination for standard PCB integration

Applications

• General purpose audible signaling in electronic equipment
• Alarm systems requiring discrete piezo elements
• Industrial control panels needing high-volume acoustic output

Procurement Notes

Verify the specific suffix or variant against the official Soberton datasheet to ensure compatibility with your drive circuit requirements. Confirm that the non-washable characteristic aligns with your manufacturing process, as this component cannot withstand aqueous cleaning cycles during PCB assembly.

Selection Notes

Select this component when a high-output, externally driven piezo element is required rather than a self-contained active buzzer. Ensure the driving circuit can supply the necessary 10V potential and handle the capacitive load at 4kHz resonance. Consider the through-hole form factor if surface-mount options are not feasible for the mechanical constraints.

Part Context

This part belongs to Soberton's line of piezoelectric buzzers and sirens. It is categorized under externally driven transducers, distinguishing it from active buzzers with built-in oscillators. The PT-2207 is designed for applications where the driver electronics are separate from the acoustic element.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other externally driven piezo transducers from Soberton or competitors based on matching voltage, frequency, and sound pressure level specifications.

FAQ

Does the PT-2207 have a built-in drive circuit?

No, the PT-2207 is an externally driven piezo transducer and requires an external circuit to generate the drive signal.

Is the PT-2207 washable?

No, the PT-2207 is specified as a non-washable type and should not be subjected to aqueous cleaning processes.
