PUI Audio 90 dBA Through Hole External Piezo Buzzer Transducer 14 mm 4 V Min 16 mm 16mm 8V Max

This piezo buzzer transducer is an electromechanical sound device designed to produce audible alerts in control and signalling systems. It operates with an external drive and is suited to industrial and electronic control panels where a compact, high‑output audible signal is required. The unit is manufactured for through‑hole mounting and complies with RoHS and REACH directives relevant to material restrictions.

• Operates between 1548 Hz and 2548 Hz for audible tone flexibility
• Produces 90 dBA SPL for distinct alerts in noisy environments
• Accepts 4V to 8V drive for low‑voltage system compatibility
• Rated to 70 °C for elevated‑temperature applications
• Through‑hole format for secure PCB attachment and mechanical stability

• Suitable for alarm panels in factory automation systems
• Ideal for machine status indication in electrical control cabinets
• Used with battery‑powered devices requiring low‑voltage signalling
• Can be used for safety alerts in HVAC and building management
• Used for audible feedback on test rigs and measurement equipment

It uses a through‑hole mounting style that provides robust soldered connections and mechanical retention during vibration.

An external drive source must be provided, the device requires a driven signal within the specified voltage and frequency range for correct operation.

The component is rated for operation up to 70 °C, allowing installation in warmer industrial enclosures where standard ambient rises occur.

The transducer has a Compact footprint with a nominal 16mm width and length and a 14mm maximum height, enabling space‑efficient placement.
