AT-0927-TT-2-R

Overview

The AT-0927-TT-2-R is an externally driven electromagnetic buzzer manufactured by PUI Audio. It features a through-hole mounting style with solder pin termination and a top-firing acoustic design. The component operates at a nominal voltage of 3 VDC, drawing a current of 70 mA. It produces a continuous tone at a resonant frequency of 2.73 kHz with a sound pressure level of 86 dBA measured at 10 cm. The physical dimensions are 9 mm in diameter and 4 mm in height.

Feature Summary

Externally driven electromagnetic transducer design
Top-firing acoustic output configuration
Through-hole mounting for PCB integration

Applications

Industrial control panels
Medical equipment status indicators
Consumer electronics alerts

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging type and lead time requirements. Ensure the receiving facility is equipped for through-hole assembly processes. Confirm compliance with RoHS and REACH regulations as specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, high-output magnetic buzzer is required for through-hole applications. The 3V operating voltage suits battery-powered or low-voltage logic circuits. Consider the 86 dBA output level against ambient noise requirements and the 70 mA current draw against power supply capabilities.

Part Context

This part belongs to PUI Audio's line of electromechanical audio indicators. It utilizes a magnetic coil and diaphragm mechanism rather than piezoelectric elements. The AI series typically includes various form factors, but this specific model is distinguished by its 9mm diameter and through-hole construction.

Replacement Considerations

Direct substitutes must match the 3V nominal voltage, 2.73 kHz frequency, and 9mm diameter. Verify that alternative components support through-hole mounting and similar current ratings. Cross-reference mechanical footprint drawings to ensure PCB compatibility.
