Overview
The AT-3411-T-HT-LW110-R is a piezoelectric buzzer transducer manufactured by PUI Audio, Inc. It operates at a nominal voltage of 9 V and features a resonant frequency of 1.1 kHz (1100 Hz). The device delivers an acoustic output of at least 85 dBA at 10 cm distance. It is housed in a compact package with a 23.2 mm flange diameter and supports board mounting via solder pins. The component is rated for a wide operating temperature range from -30°C to +85°C and has a current rating of 9 mA.
Feature Summary
- High-temperature capability designed for demanding environments
- Piezoelectric technology for reliable acoustic signaling
- Compact form factor with integrated flange for easy installation
Applications
- Industrial control panels requiring high-temperature resistance
- Medical equipment signaling systems
- Security and fire alarm indicators
Procurement Notes
Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the 9V nominal voltage and 1.1kHz resonant frequency align with your circuit design requirements. Ensure the operating temperature range meets your application's environmental conditions. Check for any specific packaging or tray requirements if applicable.
Selection Notes
Select this component when a high-output piezo buzzer is needed for applications involving elevated temperatures up to 85°C. The 9V drive requirement and 9mA current draw should be considered for power supply design. The 23.2mm flange size dictates the mechanical mounting space available on the PCB or enclosure.
Part Context
This part belongs to PUI Audio's AT series of piezoelectric transducers. The 'HT' designation indicates high-temperature construction, distinguishing it from standard variants. It is categorized under alarms, buzzers, and sirens within the audio devices product line.
