AT-4228-TWT-F-R

Overview

The AT-4228-TWT-F-R is a piezoelectric transducer from PUI Audio designed for industrial audio indication. It operates within a voltage range of 1 to 30 VDC and draws 10 mA at the rated 12 VDC. The device produces a sound pressure level of 92 dBA at a frequency of 2.8 kHz with a pulse tone. It features solder pad termination for surface mount installation and includes integrated feedback circuitry.

Feature Summary

• Integrated feedback mechanism for precise frequency control
• Surface mount design compatible with automated assembly processes
• Washable construction suitable for harsh industrial environments

Applications

• Industrial machinery status indicators
• Medical equipment audio alerts
• Consumer appliance signaling systems

Procurement Notes

Verify that the specific order matches the AT-4228-TWT-F-R designation, as suffixes may alter electrical characteristics or mounting style. Confirm RoHS compliance requirements against current regulatory standards. Ensure the procurement documentation explicitly states the inclusion of the feedback feature, which distinguishes this model from standard piezo elements.

Selection Notes

Select this component when surface mount technology is required for high-volume production lines. The integrated feedback ensures consistent acoustic output despite voltage fluctuations within the specified operating range. Consider the washable capability if the application involves cleaning cycles or exposure to contaminants.

Part Context

This transducer belongs to the SMT series of audio indicators by PUI Audio. It utilizes piezoelectric technology to convert electrical signals into audible tones. The design prioritizes reliability in demanding environments through robust construction and stable electronic performance.

Replacement Considerations

Direct substitutes must match the 2.8 kHz frequency, 92 dBA SPL, and surface mount footprint. Verify that any replacement also includes the feedback circuit to maintain signal stability.
