The AT-0927-TT-2-R is an electromechanical magnetic buzzer from PUI Audio, Inc. It is rated for 3V operation with a voltage range of 2V to 4V and draws a typical current of 70mA. The buzzer produces a single tone at a resonant frequency of 2.73kHz and provides a typical sound pressure level of 86dB at a distance of 10cm when driven with a 3V peak-to-peak signal.
The transducer requires an external driving circuit, as it does not contain an internal oscillator. The package is a 9.00mm diameter through-hole component with a height of 4.20mm. The port is located on the top, and the device terminates in PC pins for straightforward PCB mounting. The operating temperature range is -20°C to 70°C, making it suitable for a variety of indoor electronic applications.
