AT-2440-TWT-R

Overview

The AT-2440-TWT-R is a piezoelectric transducer manufactured by PUI Audio, Inc. It features a 24mm diameter housing with through-hole pin termination for PCB mounting. The device operates on an externally driven basis within a voltage range of 1 to 30V. It produces a single tone at a resonant frequency of 4kHz, with a typical sound pressure level of 80dBA measured at 3V and 10cm distance. The component utilizes a piezo-electric technology suitable for audible alert applications.

Feature Summary

Externally driven piezoelectric transducer design
Through-hole pin termination for board mounting
Single-tone audible alert generation
Wide operating voltage range capability

Applications

Appliance status indicators
Industrial control panel alerts
Security system sirens
Medical equipment audio feedback

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with PUI Audio or authorized distributors before procurement. Confirm that the external drive circuitry can support the required voltage range of 1 to 30V and current specifications. Ensure mechanical clearance allows for the 24mm diameter and appropriate height dimensions during PCB layout planning.

Selection Notes

Select this component when a compact, high-volume audible indicator is required. The 24mm form factor suits space-constrained enclosures. The externally driven nature requires an external oscillator or microcontroller output rather than internal self-oscillation. Consider the 80dBA SPL rating against ambient noise levels in the target application environment.

Part Context

This part belongs to the PUI Audio AT series of piezoelectric transducers. The series offers various diameters and mounting styles. The AT-2440-TWT-R specifically denotes the 24mm diameter variant with through-hole pins. PUI Audio specializes in audio components for industrial, medical, and consumer markets.

Replacement Considerations

Direct substitutes must match the 24mm diameter, 4kHz frequency, and through-hole pin configuration. Verify equivalent SPL ratings and voltage compatibility. Cross-reference with other manufacturers' piezo buzzers offering similar acoustic output and mechanical footprint.
