- Security system alarms
Procurement Notes
Verify the specific datasheet version for the AT-3046-TWT-2-R to confirm RoHS and REACH compliance details prior to integration. Ensure that the driving circuit provides the correct voltage and current limits to prevent damage to the piezoelectric element. Confirm mechanical mounting constraints align with the 30 mm diameter and 7.5 mm height dimensions specified in the official documentation.
Selection Notes
Select this component when a compact, high-output piezoelectric indicator is required for board-mounted designs. The 85 dBA sound pressure level offers sufficient audibility for industrial environments. Consider the 10 mA current draw and 10 V rating when designing the drive circuitry. The operating temperature range of -20°C to +60°C suits standard indoor electronic equipment applications.
Part Context
This part belongs to the AT series of transducers from PUI Audio, which specializes in audio components for various industries. The series includes both electromagnetic and piezoelectric options. The AT-3046-TWT-2-R specifically represents a piezoelectric variant with through-hole solder pin connections, distinct from surface-mount or electromagnetic alternatives in the same product line.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should verify compatibility with existing footprints and electrical requirements if considering alternative piezoelectric transducers from other manufacturers.
