Overview

The AI-1440-TWT-12V-R is a 12V internally driven piezo indicator from PUI Audio designed for reliable audible signaling in industrial and commercial electronics. It features a top-firing port and integrated circuitry that generates a 4kHz single-tone beep when a DC voltage between 3V and 16V is applied. This through-hole component is specifically designed to withstand wave soldering and aqueous cleaning processes, making it ideal for high-volume automated manufacturing.

Why Choose This Part

The component is washable and wave-solderable, which simplifies the PCB assembly process by eliminating the need for manual cleaning or secondary soldering after the wash stage. Its wide 3V to 16V operating range and low 7mA current draw at 12V make it compatible with various logic levels and battery-powered systems without requiring complex drive circuitry.

Applications

Industrial Control Panels
Provides immediate audible feedback for operator inputs or system status changes in 12V or 15V control systems.
Security and Alarm Systems
Acts as a compact sounder for entry/exit delays or fault notifications in security peripherals.
Medical Monitoring Equipment
Integrated as a non-critical alert indicator where a 4kHz tone is effective for proximity signaling.
Consumer Appliances
Used in white goods for end-of-cycle alerts or user interaction confirmation.

Getting Started

Integration is straightforward as the device is internally driven; simply apply a DC voltage within the 3V to 16V range to the PC pins to activate the sound. Ensure the top-firing port is not obstructed by the enclosure to maintain the 80dB sound pressure level. Because it is a piezo device, no external oscillator or PWM signal is required for basic operation.
