Overview
The AI-2437-TWT-R is a piezoelectric audio indicator manufactured by PUI Audio. It operates at a rated voltage of 12 VDC with a current draw of 8 mA. The device produces a continuous tone at a frequency of 3.7 kHz and achieves a sound pressure level of 100 dBA. It features through-hole solder pin termination and has physical dimensions of 24 mm in diameter and 18 mm in height.
Feature Summary
- Piezoelectric transducer technology for reliable acoustic output
- Continuous tone generation capability
- Through-hole mounting configuration for PCB integration
Applications
- Industrial control panels
- Medical equipment status indication
- Security system alerts
Procurement Notes
Verify the specific ordering suffix to ensure compatibility with required environmental ratings and compliance standards such as RoHS. Confirm that the through-hole pin spacing matches the target printed circuit board layout. Review the manufacturer datasheet for detailed mechanical drawings and electrical characteristics before finalizing component selection for production.
Selection Notes
Select this component when a high-decibel audible alert is required within a compact form factor. The 12 VDC rating suits standard logic-level power supplies. Consider the 3.7 kHz frequency for optimal human hearing sensitivity. Ensure the enclosure allows for unobstructed sound propagation from the piezo element.
Part Context
This part belongs to the AI series of audio indicators from PUI Audio, which specializes in piezoelectric sounders and transducers. The series offers various frequencies and decibel levels tailored for different industrial and consumer applications. PUI Audio provides these components for use in environments requiring robust and consistent audio signaling.
Replacement Considerations
Direct substitutes include other PUI Audio models within the AI series, such as the AI-2429-TWT-12V-3-R or AI-2331-TWT-2-R, provided the frequency and sound pressure level differences are acceptable for the application design.
