AI-3238-TF-LW140-R

Overview

The PUI Audio AI-3238-TF-LW140-R is a piezoelectric audio indicator designed for industrial applications. It operates on a nominal voltage of 12 VDC with a supply range of 3VDC to 20VDC and draws a maximum current of 10mA. The device produces a continuous tone at a resonant frequency between 3.5 kHz and 3.8 kHz, delivering a sound pressure level of 105 dBA to 106 dBA. It features wire leads for connection and utilizes flange mounting for secure installation.

Feature Summary

Piezoelectric transducer technology for reliable acoustic output
Continuous single-tone operation mode
Flange mount design with wire lead termination

Applications

Industrial machinery status indication
Equipment alarm signaling
Control panel audio alerts

Procurement Notes

Verify the specific datasheet version for the exact resonant frequency tolerance and SPL measurement distance, as sources vary between 105 dBA and 106 dBA. Confirm that the wire lead length meets your assembly requirements. Ensure the operating temperature range of -30°C to +85°C aligns with your environmental conditions before finalizing procurement.

Selection Notes

Select this component when a high-decibel audible alert is required for 12V DC systems. The wide supply voltage range allows flexibility in power distribution. The flange mount style simplifies enclosure integration compared to screw-mount alternatives. Verify that the 10mA current draw fits within your system's power budget constraints.

Part Context

This model belongs to PUI Audio's line of piezoelectric buzzers. It serves as an alternative to electromagnetic indicators where higher efficiency and lower current consumption are prioritized. The part number suffix indicates specific terminal and mounting configurations distinct from other variants in the series.

Replacement Considerations

Direct substitutes must match the 12VDC rating, flange mounting footprint, and wire lead termination. Verify that replacement parts maintain the 105+ dBA sound pressure level to ensure adequate audibility in noisy environments.
