PUI Audio Piezo Buzzer Transducer, 90dBA Sound Level, 2 to 4V Supply Voltage - AT-1127-ST-2-R


This piezo buzzer transducer is a Compact external-drive sounder designed to provide audible alerts in low-voltage control and monitoring systems. It converts an applied drive signal into a clear, high-intensity tone suitable for industrial and commercial equipment operating within moderate temperature environments.

Features and Benefits:


• 90dBA output delivers clearly audible alerts in noisy areas
• Operates from 2 to 4V for compatibility with low-voltage systems
• Frequency range 2kHz to 3.23kHz supports distinct tonal signalling
• Through-hole mount enables secure PCB installation for vibration-prone settings
• Rated to 70°C for stable operation in warm industrial locations

Applications


• Suitable for alarm circuitry in automation panels
• Ideal for status indication in control cabinets
• Used for warning signals on industrial machinery
• Can be used for audible feedback in electronic test rigs

What drive arrangement does it require?


It requires an external drive source rather than an internal oscillator, so the tone is determined by the applied signal.

How small is the component footprint on a board?


The device occupies a Compact 10.7x9.2mm envelope, allowing dense PCB layouts.

What mounting method should be used for reliable attachment?


Use through‑hole soldering to secure mechanical and electrical connection for long‑term service.

Is the product suitable where environmental directives apply?


It meets RoHS 2015/863/EU requirements, restricting specified hazardous substances.
