PT-2309

Overview

The PT-2309 is an externally driven piezoelectric transducer manufactured by Soberton Inc. It operates at a rated voltage of 10 V with a current consumption of 3 mA. The device generates sound at a frequency of 2.048 kHz, achieving a sound pressure level of 85 dB measured at 10 V. It features a 22.5 mm diameter and utilizes through-hole PC pins for mounting. The unit has a cable length of 10 cm and is designed for non-washable applications within an operating temperature range of -20°C to 70°C.

Feature Summary

• Externally driven piezoelectric construction
• Through-hole PC pin termination
• Non-washable type design

Applications

• Alarm systems
• Buzzer circuits
• Siren devices

Procurement Notes

Verify the exact part number against official Soberton Inc. documentation before procurement. Confirm that the externally driven piezo specification matches your circuit requirements. Ensure the through-hole package and 10 cm lead length are compatible with your PCB layout. Check for any specific environmental ratings if operation exceeds standard temperature limits.

Selection Notes

Select this component when a simple, externally driven piezo buzzer is required. It is suitable for applications needing a specific 2.048 kHz tone. Consider the 10 V rating and 3 mA current draw for power supply design. The non-washable nature restricts use in wash-down environments.

Part Context

This component belongs to the category of alarms, buzzers, and sirens produced by Soberton Inc. It is distinct from audio delay chips or speakers sharing similar model prefixes. The PT-2309 is specifically a piezoelectric transducer rather than an integrated circuit or electromagnetic device.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs carefully.
