AT-2440-TWT-R Description

Short technical summary and product information.

The AT-2440-TWT-R is a piezo buzzer from PUI Audio, Inc. It features an externally driven transducer that requires a peak-peak signal input. The buzzer operates at a nominal voltage of 3V with a voltage range of 1 to 30V, consuming 1mA of current. It produces a single tone at 4kHz resonant frequency with an 80dB sound pressure level measured at 10cm distance.

 

This buzzer uses piezo technology and has a top port location. It is rated washable and operates over a temperature range of -20°C to 60°C. The component is packaged in a 24.00mm diameter by 7.70mm height through-hole form factor with PC pins for termination.

 

Compliance includes RoHS3, MSL 1, and REACH unaffected as per the available data. It is suitable for use in alarms, buzzers, and sirens applications within the audio products category.
