AT-1031-TT-R

Overview

The AT-1031-TT-R is an externally driven electromagnetic transducer manufactured by PUI Audio, Inc. Designed for through-hole mounting, this component features a round shape with PC pin terminations. It operates within a voltage range of 1 to 3 volts and draws a current of 80 mA at its self-resonant frequency of 3.1 kHz. The device produces a sound pressure level of 85 dB when driven at 1.5 V. Its physical dimensions include a height of 6.5 mm, making it suitable for compact electronic assemblies requiring audible signaling.

Feature Summary

Externally driven electromagnetic design for flexible integration
Through-hole mounting with PC pin terminations for secure board attachment
Round acoustic profile optimized for standard buzzer applications

Applications

Consumer electronics audible alerts
Industrial control panel signaling
Medical device status indicators

Procurement Notes

Verify the specific datasheet version for the AT-1031-TT-R to confirm exact electrical tolerances and mechanical drawings before finalizing designs. Ensure that the driving circuit can supply the required 80 mA current at 1.5 V to achieve the specified 85 dB output. Confirm through-hole footprint compatibility with your PCB layout to avoid assembly issues.

Selection Notes

Select this component when a reliable, low-voltage audible indicator is needed for through-hole PCB designs. The 3.1 kHz resonance provides clear audibility in typical environments. Consider the 6.5 mm height constraint during enclosure design. This transducer is appropriate for applications where external drive signals are available rather than integrated oscillator buzzers.

Part Context

PUI Audio, Inc. specializes in audio components including transducers, speakers, and sirens. The AT-1031-TT-R belongs to their line of electromagnetic transducers designed for general-purpose audible signaling. These components are widely used across industrial, medical, and consumer sectors due to their robust construction and consistent performance characteristics.
