AI-1440-TWT-24V-3-R

Overview

The AI-1440-TWT-24V-3-R is a piezo transducer designed for externally-driven applications. It operates within a supply voltage range of 5 VDC to 28 VDC, with a nominal rating of 24 VDC. The device features a resonant frequency of 4 kHz and delivers a sound pressure level of 88 dBA at 24 VDC measured at 10 cm. It utilizes through-hole mounting technology and has a diameter of approximately 13.80 mm (0.543 inches).

Feature Summary

Externally driven piezo design for continuous tone generation.
High acoustic output capability suitable for audible alerts.
Robust voltage tolerance supporting 5 VDC to 28 VDC operation.

Applications

Industrial control panels requiring high-volume indicators.
Medical equipment status signaling.
Security and fire alarm systems.

Procurement Notes

Verify the specific drive circuit requirements, as this component is externally driven rather than self-oscillating. Confirm that the operating voltage remains within the 5 VDC to 28 VDC range to ensure optimal performance and longevity. Check mechanical clearance for the 13.80 mm diameter and through-hole footprint during PCB layout.

Selection Notes

Select this model when a high-decibel, continuous tone is required without internal oscillation circuitry. It is distinct from self-drive variants like the AI-1440-TWT-24V-2-R. Consider the 88 dBA output level against enclosure attenuation factors. Ensure the application can provide the necessary external square wave or AC signal at 4 kHz.

Part Context

This part belongs to PUI Audio's AI series of piezo buzzers. The 'TWT' designation typically indicates through-hole technology, while '24V' specifies the nominal voltage rating. The suffix '-3-R' often denotes specific packaging or lead configuration details within the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes may include other 4 kHz, 24 VDC externally driven piezo buzzers from PUI Audio or competitors. Verify matching SPL, voltage range, and physical dimensions. Self-drive models are not direct replacements unless the drive circuit is modified.
