AI-2429-TWT-R

Overview

The AI-2429-TWT-R is a piezoelectric audio indicator manufactured by PUI Audio. It operates at a rated voltage of 12 VDC with a current draw of 10 mA. The device produces a continuous tone at a resonant frequency of 2.9 kHz, achieving a sound pressure level of 95 dBA. It features through-hole mounting with solder pin termination. The component has a round shape with a diameter of 24 mm and a height of 16 mm.

Feature Summary

Piezoelectric transducer technology for reliable acoustic output
Continuous tone generation capability for steady-state alerts
Through-hole PCB mounting design for secure mechanical attachment

Applications

Electronic equipment status indication
Appliance operational feedback systems
Industrial control panel signaling

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure compliance with required electrical parameters and mechanical dimensions. Confirm that the through-hole package style matches the target printed circuit board layout. Check for RoHS and REACH compliance status in the latest datasheet before integration into final products.

Selection Notes

Select this component when a high-volume, cost-effective piezoelectric solution is required for audible signaling. The 12 VDC rating suits standard logic-level power supplies. Consider the 95 dBA output for environments requiring clear auditory feedback without excessive noise pollution. Ensure the 2.9 kHz frequency aligns with human hearing sensitivity for optimal alertness.

Part Context

This model belongs to the AI series of audio indicators from PUI Audio. These components are designed as direct replacements for generic piezo buzzers in consumer and industrial electronics. The series emphasizes standardized form factors and consistent acoustic performance across various operating temperatures.
