AT-202

Overview

The AT-202 is an externally driven electromechanical transducer manufactured by PUI Audio, Inc. Designed for alarm applications, this component operates at a resonant frequency of 2.048 kHz. It utilizes magnetic technology to convert electrical signals into audible sound without integrated driver circuitry. The device requires external driving electronics to function effectively within industrial or commercial alerting systems.

Feature Summary

Externally driven design requiring separate driver circuitry
Electromechanical magnetic transduction technology
Optimized for high-frequency alarm signaling

Applications

Industrial alarm systems
Commercial security alerts
Electronic warning devices

Procurement Notes

Verify the specific datasheet for mechanical dimensions and mounting requirements before integration. Confirm that the application circuit provides the necessary drive signal for the 2.048 kHz resonance. Ensure compatibility with external driver components to achieve specified acoustic output levels in the final assembly.

Selection Notes

Select this component when an externally driven solution is preferred over self-excited buzzers. The 2.048 kHz frequency offers distinct audibility for alert purposes. Consider the need for additional driver ICs or discrete components in the system design to control the transducer effectively.

Part Context

PUI Audio specializes in audio components including transducers and speakers. The AT-202 belongs to their line of externally driven alarms, providing flexibility for custom driver designs compared to integrated piezo or electromagnetic buzzers.
