AST1440MATRQ Description

AST1440MATRQ belongs to Piezo Buzzers & Audio Indicators. Audio alerts, buzzers, and indicators are a broad category of audio signaling devices. Depending on their principle of operation they can be classified as magnetic, electromechanical, mechanical, electromagnetic, piezo-electric, or electro-acoustic audio signaling devices. Audio indicators and alerts are designed to give an audio output when triggered through one or more available methods. The output from these devices can be a beep, click, or ring. Besides their underlying concept, audio indicators and alerts are also commonly categorized according to sound level, frequency range, rated voltage, packaging type, and dimension.
