PUI Audio Piezo Buzzer Transducer, 85dBA Sound Level, 1V to 3V Supply Voltage - AT-1220-TT-R
This piezo buzzer transducer serves as an audible signalling device for low-voltage systems, converting electrical drive into sound in industrial and electronic assemblies. It operates with an external drive and is suited to panel or board mounting in environments where compact, high-output alerts are required.
Features and Benefits:
• Operates from 1 to 3V to suit low-voltage control circuits
• Acoustic output around 85dBA for clear audible alerts
• Frequency range 1548 to 2548Hz to permit distinct tone selection
• Through-hole mounting for secure mechanical retention
• Rated to 70°C to withstand elevated ambient temperatures
• Acoustic output around 85dBA for clear audible alerts
• Frequency range 1548 to 2548Hz to permit distinct tone selection
• Through-hole mounting for secure mechanical retention
• Rated to 70°C to withstand elevated ambient temperatures
Applications
• Suitable for control panels requiring audible fault indicators
• Ideal for automation systems needing Compact audible alerts
• Used with sensors to provide immediate alarm feedback
• Can be used for machine-cycle completion signalling

What mounting method is provided for mechanical stability?
The device uses through-hole pins to secure it to a PCB or panel, offering robust retention against vibration and handling.
How does the acoustic characteristic fit safety signage or alarms?
The sound level of approximately 85dBA combined with a mid-kilohertz frequency band produces a perceptible tone that cuts through typical workshop noise levels.
What electrical drive considerations are required for integration?
An external drive source must supply between 1V and 3V and be capable of driving the transducer at its specified frequency band for correct operation.
How does the transducer perform under temperature stress?
It is specified to operate at ambient temperatures up to 70°C, allowing use in warmer enclosures and near heat-generating equipment.
