Overview
The AI-2604-TF-LW120-12V is a magnetic audio indicator manufactured by PUI Audio, Inc. It operates within a voltage range of 8 to 15 VDC and features a resonant frequency of 400 Hz. The device produces a continuous single tone with a sound pressure level of 79 dBA at 12 V measured at 30 cm. Electrical characteristics include a maximum supply voltage of 15 VDC and a current rating of 50 mA. The unit utilizes lead wires for connection and is designed for industrial applications requiring reliable acoustic signaling.
Feature Summary
- Magnetic transducer technology for consistent acoustic output
- Continuous single-tone operating mode
- Lead wire termination for direct circuit integration
Applications
- Industrial equipment status indication
- Control panel alarm signaling
- Appliance operational feedback
Procurement Notes
Verify the specific suffix LW120 corresponds to the required lead length for your assembly. Confirm that the 50 mA current draw is compatible with the driving circuit's capacity. Ensure the 400 Hz frequency meets the audible requirements of the target environment. Check RoHS compliance documentation if environmental regulations apply to the final product deployment.
Selection Notes
Select this component when a low-frequency 400 Hz tone is required for industrial environments. The magnetic technology offers durability compared to piezoelectric alternatives in certain mechanical stress scenarios. Consider the 12 VDC nominal voltage against available system power rails. Evaluate the 79 dBA SPL against ambient noise levels to ensure adequate audibility without excessive volume.
Part Context
This part belongs to the PUI Audio industrial indicator series, which focuses on robust components for demanding environments. The AI series typically includes various mounting styles and electrical configurations. This specific model emphasizes standard lead wire connections rather than surface mount or PCB pin headers, facilitating easy integration into existing wiring harnesses.
Replacement Considerations
Direct substitutes may include other PUI Audio models with identical 400 Hz frequency and 12 VDC operation. Verify mechanical dimensions and lead wire specifications before substitution. Cross-reference with other manufacturers offering magnetic buzzers with similar SPL and current ratings.
