AT-1224-TWT-4-R

Overview

The AT-1224-TWT-4-R is an externally driven electromagnetic transducer manufactured by PUI Audio, Inc. It operates within a voltage range of 6 V to 15 V and draws a current of 40 mA. The device features a self-resonant frequency of 2.4 kHz and produces a sound pressure level of 85 dBA. Designed for through-hole mounting, it utilizes PC pin termination. The housing is constructed from PBT (Polybutylene Terephthalate) material, ensuring durability in various environments.

Feature Summary

• Externally driven electromagnetic design for flexible control integration
• Through-hole mounting configuration with PC pin termination
• PBT housing material providing structural stability

Applications

• Industrial control panels requiring audible status indicators
• Security systems utilizing external alarm triggers
• Consumer electronics needing simple tone generation

Procurement Notes

Verify the specific operating voltage requirements against your circuit design, as this model supports a range of 6 V to 15 V. Confirm that the PCB layout accommodates through-hole pins with appropriate spacing. Ensure the enclosure allows for top-fire sound projection without obstruction. Check RoHS compliance documentation if required for your manufacturing standards. Validate mechanical dimensions against your assembly constraints before finalizing procurement.

Selection Notes

Select this component when an externally driven magnetic transducer is preferred over piezoelectric alternatives for lower impedance applications. The 2.4 kHz resonance provides clear audibility for alert tones. Consider the 85 dBA output level relative to ambient noise conditions. The PBT housing offers resistance to common environmental factors. Ensure the driving circuit can supply the required 40 mA current at voltages between 6 V and 15 V.
