Overview
The AT-0927-TT-6-R is an externally driven electromechanical transducer manufactured by PUI Audio, Inc. It operates within a supply voltage range of 2V to 4V and draws a current rating of 80mA. The device features a resonant frequency of 2.73kHz and produces a sound pressure level of 85dBA. Designed for through-hole mounting, it utilizes top-fire acoustic output. Physical dimensions are approximately 13.5mm in height with a width and length of 12mm.
Feature Summary
- Externally driven electromechanical buzzer design
- Top-fire acoustic emission configuration
- Through-hole PCB mounting capability
Applications
- Industrial control panels
- Medical equipment status indicators
- Consumer electronics alerts
Procurement Notes
Verify the specific datasheet version when ordering, as manufacturer documentation may list slight variations in resonant frequency (e.g., 2.048kHz vs 2.73kHz) or dimensional tolerances. Confirm that the external drive circuit can supply the required 80mA peak current at voltages between 2V and 4V to ensure proper operation and longevity of the component.
Selection Notes
Select this component for applications requiring a high-volume audible alert with through-hole assembly constraints. The 85dBA output provides sufficient audibility for general industrial environments. Ensure the host board layout accommodates the 12x12mm footprint and allows for unobstructed top-fire sound propagation without mechanical interference from adjacent components.
Part Context
This part belongs to PUI Audio's line of electromechanical transducers, which are distinct from piezoelectric alternatives. These devices rely on magnetic coil movement to generate sound, offering robust performance in standard audio indicator roles. The series is commonly utilized in sectors requiring reliable, cost-effective acoustic signaling solutions.
Replacement Considerations
The AT-0927-TT-5-R is a related variant within the same product family. Verify electrical compatibility and acoustic specifications before substitution, as differences in resonant frequency or drive requirements may exist between these closely numbered parts.
