Overview
The AI-1223-TWT-5V-6-R is an internally driven electromagnetic transducer manufactured by PUI Audio. It operates at a nominal voltage of 5 VDC with a current draw of 30 mA. The device produces a continuous sound tone at a resonant frequency of 2.3 kHz, achieving a sound pressure level of 85 dBA measured at 10 cm. It utilizes through-hole PC pin termination for PCB mounting and features an internal magnetic circuit design.
Feature Summary
- Internally driven electromechanical construction
- Continuous single-tone operation mode
- Through-hole PC pin terminal configuration
Applications
- Alarm circuits in machinery control panels
- General audio indication tasks
- Embedded system status signaling
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical tolerances and acoustic output specifications. Ensure the through-hole footprint matches the target PCB layout dimensions. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current lifecycle status before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, internally driven buzzer is required for direct logic-level or simple driver interface applications. The 5 VDC rating suits standard digital logic systems. Consider the 85 dBA output level relative to ambient noise requirements. Verify that the 2.3 kHz frequency aligns with human hearing sensitivity for alert purposes. Ensure mechanical clearance accommodates the physical dimensions of the transducer housing.
Part Context
This model belongs to the PUI Audio AI series of audio indicators. These components are designed for board-mount integration in electronic assemblies. The series offers various voltage and acoustic options to suit different embedded application needs. The AI-1223 variant specifically denotes the form factor and acoustic performance characteristics within the broader product portfolio.
Replacement Considerations
Direct substitutes include the AI-1223-TWT-5V-R and AI-1223-TWT-5V-5-R from the same manufacturer. Verify that alternative part numbers maintain identical voltage, current, and acoustic specifications. Ensure mechanical compatibility regarding pin spacing and housing dimensions before implementing any cross-references.
