Overview
The AI-1223-TWT-5V-3-R is an internally driven electromagnetic alarm sound transducer manufactured by PUI Audio. It operates on a rated voltage of 5 VDC with a current consumption of 30 mA. The device produces a continuous tone at a frequency of 2.3 kHz and delivers a sound pressure level of 85 dBA measured at 10 cm. Designed for through-hole mounting, it features solder pin termination. The unit is housed in a compact form factor suitable for panel or board installation.
Feature Summary
- Internally driven electromagnetic technology for simplified circuit integration
- Continuous single-tone audio output capability
- Through-hole solder pin termination for secure PCB mounting
Applications
- Electronic equipment status indicators
- Appliance audible alerts
- Industrial control panel signaling
Procurement Notes
Verify the specific suffix '3-R' against official PUI Audio documentation to confirm reel packaging specifications and quantity per package. Ensure the operating voltage range of 3 to 7 VDC aligns with the target system power supply. Confirm RoHS compliance requirements match project standards before finalizing procurement orders.
Selection Notes
Select this component when an internally driven, high-volume electromagnetic buzzer is required for 5 VDC systems. The 2.3 kHz frequency provides distinct audibility for general purpose alarms. Compare the 85 dBA SPL requirement against ambient noise levels to ensure adequate alert volume. Verify that through-hole mounting constraints fit within the mechanical design envelope.
Part Context
This part belongs to the AI series of audio indicators from PUI Audio. The series includes various voltage ratings and acoustic outputs. The AI-1223-TWT-5V-3-R specifically denotes the 5 VDC variant with electromagnetic technology. It is distinct from piezoelectric models in the same family regarding drive requirements and acoustic characteristics.
Replacement Considerations
Cross-reference with AI-1223-TWT-5V-R for similar electrical specifications but verify packaging differences. Check AI-1223-TWT-5V-6-R for alternative reel configurations. Ensure any substitute maintains the 2.3 kHz frequency and 85 dBA SPL to preserve acoustic performance.
