PUI Audio Piezo Buzzer Transducer, 28.5mm Diameter, 93 dBA Sound Level - AT-2830-TWT-R

This piezo buzzer transducer provides an audible signalling solution for control panels and equipment in automation and electrical systems. It operates from a low-voltage supply and produces a clear acoustic output suitable for alarms and alerts in industrial and mechanical environments. The design accommodates through-hole mounting for straightforward panel or board integration.

Features and Benefits:

• Operating range 3 to 28V enables flexible supply options
• Sound pressure level 93dBA delivers clear audible alerts
• Low supply current 8mA minimises power drain
• Maximum frequency 3500Hz supports attention-grabbing tones
• Wide operating temperature -30 to 85°C sustains harsh environments
• High-sensitivity 20,000 pF piezo element improves response to drive signals

Applications

• Suitable for industrial control panel alarms and warnings
• Ideal for factory automation alerting and fault signalling
• Used for safety annunciation in machinery and equipment rooms
• Can be used for instrumentation and test apparatus alerts

What mounting method does it require for installation?

It is designed for through-hole mounting using a standard PCB or panel hole and secured in place by soldered termination leads.

What termination materials are used for reliable connections?

The device employs Au-plated phosphor bronze terminations to provide corrosion-resistant electrical contacts.

Which thermal limits define safe operating conditions?

The unit functions between -30°C and 85°C, so it should be installed where ambient temperatures remain within this range.

How does the drive type affect integration with control electronics?

It requires an external drive signal, allowing designers to control tone timing and modulation from existing circuitry.
