PUI Audio Piezo Buzzer Component, 23.8mm Diameter, 100dB Sound Level - AI-2429-TWT-R
This piezo buzzer component provides an audible continuous tone for signalling and alert systems in industrial and electronic assemblies. It is a Compact through-hole device designed to operate across a wide supply range and is suited to equipment that requires a high-decibel acoustic output from a small footprint.
Features and Benefits:
• 100dB sound level delivers loud audible alerts for noisy environments
• 3V to 20V supply range enables flexible integration with varied control voltages
• 9mA supply current minimises power draw for low-power systems
• 3400Hz maximum frequency produces a clear continuous tone for quick recognition
• Internal drive reduces external circuitry complexity and assembly time
• Tin-plated termination ensures secure solder joints and corrosion resistance
• 3V to 20V supply range enables flexible integration with varied control voltages
• 9mA supply current minimises power draw for low-power systems
• 3400Hz maximum frequency produces a clear continuous tone for quick recognition
• Internal drive reduces external circuitry complexity and assembly time
• Tin-plated termination ensures secure solder joints and corrosion resistance
Applications
• Suitable for industrial automation alarms on control panels
• Ideal for fault indication in electrical switchgear assemblies
• Used for status alerts in mechanical machinery enclosures
• Can be used for bespoke electronics requiring Compact signalling
• Used with low-power controllers that demand minimal current draw

What mounting method is used for secure PCB attachment?
The device uses through-hole mounting to provide mechanically robust attachment and reliable solder connections.
How does the component cope with ambient temperature variation?
It is specified to operate across an ambient range from -20°C to 60°C enabling use in temperate industrial settings.
What tone behaviour should be expected during operation?
The unit produces a continuous tone rather than intermittent beeps, suitable for steady alarm conditions.
Which materials are present at the terminations for solderability?
The terminations are finished with tin-plated red copper to aid solderability and maintain electrical contact.
Are there regulatory substance considerations affecting procurement?
The part conforms to RoHS and REACH Ex.7c-1 requirements regarding restricted substances.
