AI-2429-TWT-3P-R

Overview

The AI-2429-TWT-3P-R is an internally driven piezoelectric indicator manufactured by PUI Audio, Inc. It operates at a rated voltage of 12 VDC with a current draw of 7 mA and produces a continuous tone at a frequency of 2.9 kHz. The device achieves a sound pressure level of 90 dB at 12V measured at 10 cm. It features through-hole solder pin termination and has physical dimensions of 24 mm in diameter and 16 mm in height.

Feature Summary

• Internally driven piezoelectric technology for simplified circuit integration
• Continuous tone output capability for steady-state audio signaling
• Through-hole mounting configuration with solder pin termination

Applications

• Appliance status indication
• Industrial control panel alerts
• Security system notifications

Procurement Notes

Verify the specific ordering suffix to ensure correct acoustic and electrical characteristics. Confirm that the through-hole package style matches the target PCB layout requirements. Check RoHS compliance documentation for regulatory adherence in restricted jurisdictions. Ensure the operating voltage range aligns with the system power supply specifications before procurement.

Selection Notes

Select this component when an internally driven solution is required to reduce external driver complexity. The 12 VDC rating suits standard low-voltage DC systems. Consider the 2.9 kHz frequency for optimal audibility in typical ambient noise environments. Verify mechanical clearance for the 24 mm diameter and 16 mm height within the enclosure design constraints.

Part Context

This part belongs to the AI series of audio indicators from PUI Audio, Inc., a manufacturer specializing in piezo benders, speakers, and sirens. The company provides components for medical, industrial, and consumer electronics applications. The AI series typically offers various voltage and acoustic options for general-purpose alerting needs.

Replacement Considerations

Cross-reference with other internally driven piezo buzzers from PUI Audio or competitors. Ensure replacement parts match the 12 VDC rating, 2.9 kHz frequency, and through-hole pin spacing. Verify that the replacement maintains similar sound pressure levels and physical dimensions for direct fitment.
