Overview
The AI-400 is a piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates at a nominal voltage of 12 VDC with an internal driver circuitry for direct connection. The device produces a continuous tone at a resonant frequency of 2800 Hz. Acoustic performance includes a sound pressure level of 99 dBA. Electrical characteristics specify a current draw of 8 mA. The component utilizes through-hole mounting and features wire leads for termination. Physical dimensions are approximately 23 mm in diameter and 17 mm in height.
Feature Summary
- Integrates internal driver circuitry for simplified system integration
- Generates continuous acoustic alerts via piezoelectric mechanism
- Designed for board mount installation using wire lead terminations
Applications
- Industrial control panels requiring audible status indicators
- Medical equipment alarm systems
- Security and fire detection devices
Procurement Notes
Verify the part status carefully as the AI-400 is listed as obsolete in multiple distributor databases. Confirm availability of alternative sources or final time buys if immediate procurement is required. Ensure that the specific suffix or revision matches the design requirements, as obsolescence may limit long-term supply chain stability for new production runs.
Selection Notes
Select this component when a high-decibel, internally driven piezo buzzer is needed for 12V DC applications. The 99 dBA output ensures audibility in noisy environments. Consider the physical size constraints of the 23mm diameter housing. Verify compatibility with existing PCB layouts due to the through-hole wire lead configuration rather than surface mount options.
Part Context
The AI-400 belongs to the AI series of audio indicators from PUI Audio, Inc., which specializes in piezoelectric buzzers and sirens. This series is designed for industrial and commercial applications requiring reliable acoustic signaling. The manufacturer has over 40 years of experience in audio components, providing standard and custom solutions for various electronic sectors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult the manufacturer directly for recommended cross-references or newer generation replacements within the AI series or other compatible product lines.
