Overview
The AI-2437-TT-2-R is a piezoelectric audio indicator manufactured by PUI Audio, Inc. It operates at a nominal voltage of 12 VDC with a current rating of 8 mA. The device produces a continuous tone at a frequency of 3.7 kHz and achieves a sound pressure level of 90 dBA. Designed for through-hole mounting, it features PC pin termination. The transducer has a diameter of 24 mm and measures 7.5 mm in height.
Feature Summary
- Generates a continuous audible tone via internal piezoelectric mechanism
- Utilizes through-hole PC pin termination for secure board attachment
- Provides high-intensity acoustic output suitable for alarm applications
Applications
- Industrial equipment status indicators
- Consumer appliance alarm systems
- Medical device auditory alerts
Procurement Notes
Verify the specific suffix requirements against the official PUI Audio datasheet to ensure correct electrical characteristics. Confirm that the through-hole footprint matches the target PCB layout. Check RoHS compliance status as indicated in the latest manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when a 12 VDC driven piezoelectric indicator is required. Ensure the application environment supports the specified operating temperature range. Verify that the 3.7 kHz frequency aligns with human hearing sensitivity for the intended alert purpose. Confirm mechanical clearance allows for the 24 mm diameter housing.
Part Context
This part belongs to the PUI Audio line of piezoelectric transducers designed for board-mount audio indication. These components are engineered for reliability in electronic assemblies requiring clear auditory feedback. The series offers various voltage and frequency options to suit different system power architectures and acoustic requirements.
Replacement Considerations
Cross-reference with other PUI Audio models sharing the 24 mm diameter and 12 VDC rating. Verify equivalent sound pressure levels and frequency responses to maintain acoustic performance standards during substitution.
