AI-384

Overview

The AI-384 is an internally driven piezo buzzer from PUI Audio, designed for panel mounting applications. It operates at a nominal voltage of 220 VAC and produces a sound pressure level of 95 dB at a frequency of 2800 Hz. The component features a circular form factor with a diameter of 42.5 mm (1.673 inches) and a maximum seated height of 33.00 mm (1.299 inches). Electrical connections are provided via screw terminals and quick connect tabs measuring 6.50 mm (0.256 inches) in width.

Feature Summary

Internally driven piezoelectric design eliminates the need for external oscillators
Panel mount construction with secure screw terminal and quick connect tab interfaces
High acoustic output capability suitable for industrial alerting environments

Applications

Industrial machinery status indicators
Electrical control panel alarms
Heavy equipment operational alerts

Procurement Notes

Verify that the required operating voltage matches the 220 VAC specification to prevent damage. Confirm interface compatibility with existing wiring harnesses, specifically checking for both screw terminal and quick connect tab requirements. Ensure panel cutout dimensions accommodate the 42.5 mm diameter. Check RoHS compliance status if environmental regulations apply to your specific deployment region.

Selection Notes

Select this component when high-volume audible signaling is required without complex driver circuitry. The internal drive mechanism simplifies PCB or chassis layout by removing active components. Consider the physical dimensions against available panel space. Evaluate the 95 dB output against ambient noise levels to ensure audibility. Verify that the 220 VAC input aligns with the system's power distribution architecture.

Part Context

This part belongs to the AI series of audio indicators from PUI Audio, Inc., which focuses on reliable piezoelectric signaling solutions. The series typically includes various voltages and frequencies tailored for different industrial and commercial needs. The AI-384 specifically targets higher voltage AC applications, distinguishing it from low-voltage DC counterparts within the broader product family.
