AI-2429-TWT-12V-2-R

Overview

The AI-2429-TWT-12V-2-R is a piezoelectric buzzer manufactured by PUI Audio. It operates on a 12 VDC supply with an internal driver for self-drive functionality. The component produces a continuous tone at a frequency of 2.9 kHz. Acoustic performance reaches 100 dBA at the rated voltage. Electrical current draw is specified as 8 mA to 10 mA depending on the source documentation. Physical dimensions are approximately 23.8 mm to 24 mm in diameter and 16 mm in height. Termination is achieved via solder pins for through-hole mounting.

Feature Summary

• Integrated internal oscillator enables direct connection to DC power sources without external drive circuitry.
• Piezoelectric transducer technology provides reliable acoustic signaling with low power consumption.
• Through-hole termination style facilitates secure mechanical attachment and electrical connection to printed circuit boards.

Applications

• Electronic equipment status indication
• Appliance operational alerts
• Industrial control panel signaling

Procurement Notes

Verify the specific datasheet version, as some sources list 8 mA while others indicate 10 mA current rating. Confirm that the 100 dBA specification aligns with your acoustic requirements. Ensure the through-hole pin spacing matches your PCB layout. Cross-reference the exact part number suffix to confirm the 12VDC variant and internal driver inclusion.

Selection Notes

Select this component when a self-driven audible alert is required for 12VDC systems. The 2.9 kHz frequency offers distinct audibility. Verify that the 24 mm diameter fits within the available enclosure space. Consider the 16 mm height constraint for vertical clearance. The through-hole package is suitable for standard manufacturing processes requiring robust mechanical anchoring.

Part Context

This device belongs to the AI series of audio indicators from PUI Audio. These components are designed for board-mount applications requiring simple integration. The series typically includes various diameters and frequencies to suit different acoustic needs. The AI-2429 variant specifically targets mid-range acoustic output requirements in compact form factors.

Replacement Considerations

Check for compatible piezoelectric buzzers with similar 12VDC ratings and 2.9 kHz frequencies. Ensure substitute parts maintain the same through-hole pin configuration and physical envelope dimensions. Verify that replacement units also feature internal drivers if external oscillators are not present in the design.
