AT-4328-P-R

Overview

The AT-4328-P-R is an externally driven piezoelectric transducer manufactured by PUI Audio, Inc. It operates within a voltage range of 1 to 20 V and draws a supply current of 10 mA. The device produces a sound pressure level of 95 dB at 12 V measured from a distance of 10 cm. Its resonant frequency is 2.8 kHz. The unit features panel mount installation with top port location and utilizes screw terminal or quick connect tab (0.256 inch) for electrical connection. It supports single-tone operation and functions reliably between -20°C and +70°C.

Feature Summary

• Externally driven piezoelectric design for reliable audio signaling
• Panel mount construction with top port location for direct acoustic output
• Dual termination options including screw terminals and quick connect tabs
• Single-tone operation capability for alarm and indicator applications

Applications

• Industrial control panel alarms
• Appliance status indicators
• Medical equipment audio feedback
• Automotive dashboard warning systems

Procurement Notes

Verify the specific termination style required for your assembly, as the component supports both screw terminals and quick connect tabs. Confirm that the operating environment stays within the specified temperature range of -20°C to +70°C. Ensure the driving circuit can provide the necessary 10 mA current at voltages between 1 V and 20 V. Check for any specific mounting hole dimensions required for the panel mount configuration before finalizing the design.
