Overview
The AT-2336-TWT-R is a piezoelectric transducer manufactured by PUI Audio, designed for board mount applications. It operates with an external driver and features a single-tone continuous sound output. The component has a voltage rating of 12 VDC and a current rating of 10 mA. Its acoustic performance includes a sound pressure level of 90 dBA at 12V measured at 10cm. The self-resonant frequency is specified at 3.6 kHz. The unit utilizes solder pin termination for through-hole installation and is constructed with an ABS cone material.
Feature Summary
- Piezoelectric technology with integrated feedback mechanism
- External driver requirement for operation
- Single-tone continuous audio output
- Through-hole PCB mounting via solder pins
Applications
- Electronic device status indicators
- Audible alerts in consumer electronics
- Security system sirens
- Industrial equipment signaling
Procurement Notes
Verify the specific datasheet version to confirm compliance details such as RoHS and REACH status, as these are listed as detailed rather than absolute values in source records. Confirm that the application circuit supports the required external driving voltage and current specifications. Ensure mechanical clearance accommodates the physical dimensions provided in the official documentation before finalizing the design.
Selection Notes
Select this component when a high-intensity audible alert is required from a compact form factor. The 90 dBA output level makes it suitable for noisy environments where standard buzzers may be insufficient. The external driver requirement allows for flexible control logic integration but necessitates additional circuitry compared to internal oscillator models. Verify that the 12 VDC supply aligns with the target system's power architecture.
Part Context
This part belongs to the AT series of transducers from PUI Audio, which focuses on piezoelectric and electromagnetic audio devices. The AT series is characterized by its versatility in both speaker and transducer configurations. This specific model emphasizes high sound pressure levels for alerting purposes rather than music reproduction or low-volume indication.
FAQ
