Overview
The AI-2628-TF-LW100-WP-R is a piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates on a nominal voltage of 12 VDC with a current rating of 35 mA. The device produces a continuous tone at a frequency of 2.8 kHz (2800 Hz). It delivers a sound pressure level of 85 dBA and functions within a voltage range of 6 to 14 volts. The transducer features wire lead terminations and panel mounting capabilities.
Feature Summary
- Piezoelectric transducer design for reliable acoustic output
- Continuous tone generation capability
- Panel mounting configuration with flange style
- Wire lead termination for circuit integration
Applications
- Industrial equipment status indication
- Alarm systems requiring audible alerts
- Consumer appliance feedback indicators
- Control panel audio signaling
Procurement Notes
Verify the specific suffix WP-R against official PUI Audio documentation to confirm water-resistant or weather-proof characteristics if required for the application environment. Ensure the operating voltage range of 6 to 14 volts aligns with the system power supply. Confirm that the 35 mA current draw is supported by the driving circuitry without exceeding component limits.
Selection Notes
Select this component when a continuous tone indicator is required rather than intermittent beeping. The 85 dBA output provides sufficient audibility for general industrial environments. The 12 VDC nominal voltage makes it suitable for standard DC-powered systems. Consider the physical dimensions and panel cutout requirements associated with the flange mounting style during enclosure design.
Part Context
This part belongs to the PUI Audio AI series of piezoelectric buzzers. The series includes various models with different voltages, frequencies, and sound levels. The AI-2628 variant specifically denotes the 2.8 kHz frequency characteristic. Other suffixes in the series may indicate variations in termination style or environmental sealing.
Replacement Considerations
Direct substitutes must match the 12 VDC nominal voltage, 2.8 kHz frequency, and 85 dBA sound pressure level. Verify that alternative components support the same wire lead termination and panel mounting form factor. Check for equivalent current ratings to ensure compatibility with existing drive circuits.
