Overview
The AI-1027-TWT-12V-R is a through-hole, internally driven electromagnetic buzzer manufactured by PUI Audio. It operates at a nominal voltage of 12 VDC with a current draw of 60 mA. The device produces a continuous tone at a frequency of 2.7 kHz and achieves a sound pressure level of 85 dBA when measured at a distance of 10 cm. The unit features a compact 9.5 mm diameter form factor with solder pin termination for standard PCB mounting.
Feature Summary
- Internally driven electromagnetic design eliminates the need for external oscillators
- Continuous tone output suitable for steady-state audio alerts
- Through-hole construction with solder pin termination for robust board attachment
Applications
- Electronic equipment status indication
- Appliance control panel signaling
- Industrial machinery fault alarms
Procurement Notes
Verify that the required acoustic performance aligns with the specified 85 dBA rating at 10 cm. Confirm that the 60 mA current consumption fits within the target circuit's power budget. Ensure the PCB layout accommodates the 9.5 mm diameter footprint and through-hole spacing. Check compliance documentation for RoHS and REACH requirements relevant to the destination market.
Selection Notes
Select this component when an integrated, self-exciting magnetic buzzer is preferred over piezoelectric types. The 12 VDC rating suits systems with stable DC power rails. Consider the 2.7 kHz frequency for optimal human audibility in noisy environments. Evaluate the 60 mA load against available driver capacity on the control interface.
Part Context
This part belongs to PUI Audio's AI series of audio indicators. It utilizes electromagnetic transduction technology rather than piezoelectric ceramics. The internal drive circuitry simplifies integration by removing the requirement for external driving signals or oscillator components.
Replacement Considerations
Cross-reference with other internally driven magnetic buzzers from PUI Audio such as the AI-1223-TWT-12V-R for larger form factors. Verify compatibility with alternative suppliers offering similar 12 VDC electromagnetic buzzers, ensuring matching voltage, current, and acoustic specifications.
