AI-1440-TWT-24V-2-R

Overview

The AI-1440-TWT-24V-2-R is a self-drive audio indicator manufactured by PUI Audio, Inc. It operates at a nominal voltage of 24 VDC with a current draw of 18 mA. The device produces a continuous sound pressure level of 87 dBA at a frequency of 4 kHz. It features a 14 mm diameter form factor and utilizes through-hole mounting for board integration. The unit is designed for direct connection to power sources without external drivers.

Feature Summary

• Self-driven operation eliminates the need for external oscillator circuits
• Continuous tone generation capability for steady-state alerts
• Through-hole termination style for secure PCB attachment

Applications

• Embedded system status indication
• Industrial control panel signaling
• Medical equipment operational alerts

Procurement Notes

Verify that the supply voltage matches the 24 VDC specification to ensure proper operation. Confirm that the PCB layout accommodates the through-hole pin configuration and the 14 mm diameter footprint. Ensure the application environment does not exceed the acoustic requirements defined by the 87 dBA rating. Check RoHS compliance documentation if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a simple, driver-free audible alert is required for 24 VDC systems. The 4 kHz frequency provides clear audibility in moderate noise environments. Consider the physical dimensions and mounting style during mechanical design. This part is suitable for applications where low complexity and reliable continuous signaling are prioritized over variable tone capabilities.

Part Context

This indicator belongs to PUI Audio's line of self-drive transducers designed for straightforward integration into electronic assemblies.
