AT-4034-TT-R

Overview

The AT-4034-TT-R is a self-driven piezoelectric transducer designed for audible signaling applications. It operates at a rated voltage of 9 VDC and draws a current of 10 mA. The device produces a sound pressure level of 90 dBA at a resonant frequency of 3.4 kHz. It features through-hole solder pin termination and measures 30 mm in diameter with a height of 7.5 mm.

Feature Summary

• Self-driven internal piezo element eliminates need for external drivers
• Through-hole mounting for secure PCB integration
• High acoustic output for clear audible alerts

Applications

• Alarm systems
• Audible indicators
• Appliance signaling

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and compliance status. Confirm that the through-hole pin configuration matches the target PCB footprint. Check RoHS and REACH documentation for regulatory requirements. Ensure the operating voltage aligns with the system design to prevent damage or insufficient performance.

Selection Notes

Select this component when an internally driven solution is required to simplify circuit design. The 9 V rating suits standard logic-level power supplies. Consider the 3.4 kHz frequency for optimal human hearing sensitivity. Verify mechanical clearance for the 30 mm diameter and 7.5 mm height constraints.

Part Context

PUI Audio manufactures audio components including transducers, speakers, and sirens. The AT series represents their line of piezoelectric buzzers. This model is part of their standard product offering for industrial and consumer electronics signaling needs.

Replacement Considerations

Check for direct substitutes from PUI Audio with similar voltage and frequency ratings. Verify compatibility with existing PCB layouts if swapping between different package types.
