PT-2309A

Overview

The PT-2309A is an externally driven piezo transducer manufactured by Soberton Inc. It operates within a voltage range of 3 to 30V, with a rated voltage of 10V. The device draws 3.5mA at the rated voltage and produces a sound pressure level of 85dB at 10V measured from a distance of 10cm. Its resonant frequency is 2kHz. The component utilizes through-hole mounting with PC pins and accepts peak-peak signals.

Feature Summary

• Externally driven piezoelectric technology for audio signal generation
• Through-hole construction with PC pin termination
• Capable of producing high-decibel output levels suitable for audible alarms

Applications

• Industrial alarm systems requiring clear audio indicators
• Electronic devices needing external buzzer integration
• Safety equipment signaling mechanisms

Procurement Notes

Verify the specific part number suffix against official Soberton Inc. documentation to ensure correct electrical characteristics. Confirm that the required operating voltage aligns with the 3-30V range. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the through-hole package dimensions fit your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when an externally driven solution is preferred over integrated driver buzzers. The 85dB output at 10V makes it suitable for environments requiring distinct auditory alerts. Consider the 2kHz frequency response for tone clarity. The through-hole format is appropriate for prototyping or applications requiring robust mechanical mounting compared to surface-mount alternatives.

Part Context

This transducer belongs to the Soberton Inc. line of piezo buzzers designed for industrial and commercial signaling. It serves as a standalone acoustic element requiring external circuitry for operation. The product series typically includes variants with different voltage ratings and sound pressure levels to accommodate diverse application requirements across various electronic assemblies.

Replacement Considerations

Direct substitutes may include other externally driven piezo transducers with similar 85dB output and 2kHz frequency. Verify mechanical footprint compatibility for through-hole mounting. Ensure replacement parts support the same 3-30V input range. Cross-reference datasheets for exact pinout and terminal specifications to maintain circuit functionality.
