Overview
The AT-3237-TF-LW140-R is an externally driven piezoelectric transducer manufactured by PUI Audio. It operates at a nominal voltage of 12 VDC and produces a continuous tone at a frequency of 3.7 kHz. The device delivers a sound pressure level of 98 dBA with a rated current consumption of 7 mA. It features wire lead termination and flange mount installation style. Physical dimensions include a diameter of 32 mm, height of 17 mm, and length of 33 mm. The unit weighs approximately 7 grams and belongs to the AI series.
Feature Summary
- Externally driven piezoelectric design for reliable audio indication
- Continuous tone output optimized for industrial environments
- Flange mount configuration for secure panel integration
Applications
- Industrial control panels
- Medical equipment status indicators
- Security system alerts
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation before integration. Ensure drive circuitry matches the 12 VDC rating and 7 mA current specification to prevent damage. Validate mechanical mounting requirements against the flange mount design constraints.
Selection Notes
Select this model when a high-intensity audible alert is required for panel-mounted applications. The 98 dBA output ensures audibility in noisy industrial settings. Choose based on the need for external driving capability rather than internal oscillator integration. Consider the 3.7 kHz frequency for optimal human perception in alarm scenarios.
Part Context
This transducer is part of PUI Audio's comprehensive line of audio components, including buzzers, sirens, and microphones. The company specializes in innovative sound solutions for medical, industrial, and consumer electronics markets. The AI series represents their standard industrial-grade indicators designed for durability and performance.
Replacement Considerations
The AI-2337-TF-LW115-R is a similar industrial indicator from the same manufacturer. Both share the 3.7 kHz frequency and 12 VDC operation but differ in sound pressure level (100 dBA vs 98 dBA) and physical dimensions. Verify mounting compatibility and acoustic requirements when substituting.
