PUI Audio Piezo Buzzer Component, 23.8mm Diameter, 100dBA Sound Level - AI-2429-TWT-12V-2-R
This piezo buzzer component produces audible alerts for electronic and industrial control systems. It operates across a wide supply range and emits a single‑tone sound suitable for signalling in automation and electrical assemblies. The device is a through‑hole component with plated terminations and is specified for routine industrial temperature ranges.
Features and Benefits:
• High sound pressure level 100dBA for clear audible signalling
• Operates from 3V to 20V enabling flexible supply options
• Peak frequency 3400Hz to ensure distinct alarm tonality
• Low supply current 8mA minimises power draw in battery systems
• Tin‑plated red copper termination for secure solder joints
• Rated for -20 to 70°C to withstand typical industrial environments
• Operates from 3V to 20V enabling flexible supply options
• Peak frequency 3400Hz to ensure distinct alarm tonality
• Low supply current 8mA minimises power draw in battery systems
