AI-380H

Overview

The AI-380H is a piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates at a nominal voltage of 12VDC and produces a sound pressure level of 107dBA at a frequency of 2900Hz. The component features panel mounting with a diameter of 42.5mm. Designed for industrial applications, it provides reliable acoustic signaling within standard electronic systems.

Feature Summary

Piezoelectric transduction mechanism for high-intensity sound generation
Panel mount design for secure enclosure integration
Industrial-grade construction for durable operation

Applications

Industrial machinery status indicators
Control panel alarm systems
Electronic equipment auditory feedback

Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and mechanical dimensions before integration. Ensure the mounting hole size matches the 42.5mm specification. Confirm RoHS compliance requirements align with project standards. Validate that the 12VDC operating voltage is compatible with the target circuit supply rails.

Selection Notes

Select this component when high decibel output is required in a compact form factor. The piezoelectric type offers distinct advantages over electromagnetic alternatives regarding power efficiency and volume. Consider the panel mounting style if space constraints preclude board-mounted solutions. Evaluate the 2900Hz frequency response against human hearing sensitivity for optimal audibility.

Part Context

This part belongs to PUI Audio's line of buzzers and audio indicators. It serves as a specialized solution for environments requiring clear, loud auditory alerts. The manufacturer specializes in custom and standard audio components for medical, industrial, and consumer sectors.
