PUI Audio 80 dBA Through Hole Continuous Internal 13 mm Piezo Buzzer Component 13.8 mm 3 V dc Min 16V dc Max

This piezo buzzer component provides an audible continuous-tone alert for electronic and electromechanical systems, delivering a clear alarm signal within industrial environments. It is a through-hole sounder designed to operate across a wide supply range and produce a recognisable sound level suitable for control panels, alarms and warning devices.

• Operates from 3V to 16V DC supporting varied supply rails
• Produces a continuous tone at a high-frequency 4500Hz for distinct alerts
• Draws 7mA offering low current consumption for power-sensitive designs
• Emits 80dBA sound level to ensure audible detection in noisy areas
• Tin-plated red copper termination for robust soldering and connectivity
• Rated for -20°C to 70°C operation for use in varied temperature conditions

• Suitable for industrial control panel audible alarms
• Ideal for machinery fault indication and process alerts
• Used with access control and security signalling circuits
• Can be used for instrumentation and monitoring enclosures
• Suitable for retrofit alarm upgrades in mechanical systems

It uses through-hole mounting with leaded termination for insertion and wave or hand soldering.

Its external form has a diameter of 13.8mm and a height of 7.5mm to fit confined spaces.

The device emits a continuous single-frequency tone rather than intermittent or pulsed sounds.

The terminations are tin-plated red copper, suitable for standard soldering processes and good wetting characteristics.

At an operating current of 7mA, it minimises power draw, helping preserve battery life during signalling.
