AI-1450-T-WP-LW80-R

Overview

The AI-1450-T-WP-LW80-R is an internally driven piezoelectric audio indicator manufactured by PUI Audio. It operates on a rated voltage of 12 VDC with an operating range of 9 to 16 VDC. The device produces a continuous tone at a frequency of 5 kHz and delivers a sound pressure level of 80 dBA. Electrical characteristics include a current draw of 35 mA at the rated voltage. The component features wire leads for connection and is designed for through-hole mounting.

Feature Summary

• Internally driven active buzzer design eliminates the need for external oscillators
• Piezoelectric transducer technology ensures reliable acoustic output
• Continuous tone generation capability for steady-state audio signaling

Applications

• Industrial control panels requiring visual-audio status indication
• Medical equipment alarm systems
• Consumer electronics user interface feedback

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest datasheet to confirm electrical parameters and lead type. Ensure the operating voltage range aligns with the system power supply. Confirm mechanical dimensions and mounting requirements match the enclosure design before finalizing procurement.

Selection Notes

Select this component when a self-contained, internally driven audio signal is required without complex driver circuitry. The 12 VDC rating suits standard industrial logic levels. Consider the 80 dBA output and 5 kHz frequency for audibility in moderate noise environments. Verify that the wire lead termination style fits the assembly process.

Part Context

This part belongs to the AI series of audio indicators from PUI Audio, Inc., a manufacturer specializing in piezo benders, speakers, and sirens. The series typically includes various diameters and drive configurations. This specific model represents a compact, internally driven solution within their broader portfolio of audio components.

Replacement Considerations

Cross-reference with other internally driven piezo buzzers having similar 12 VDC ratings and 80 dBA SPL. Verify pinout compatibility if replacing existing assemblies. Check mechanical footprint constraints as alternative parts may differ in diameter or height.
