PUI Audio 90 dBA Through Hole External 22 mm Piezo Buzzer Transducer 23.8 mm 2 V Min 30V Max

This piezo buzzer transducer emits audible alerts for electrical and mechanical systems, converting an external drive signal into a high-level tone suitable for industrial and automation contexts. It is built for through-hole mounting and designed to operate across a broad temperature range, making it appropriate for integration into control panels, signalling assemblies and equipment requiring a distinct audio cue.

• High sound output delivers 90dBA at typical operating conditions
• Wide frequency capability reaches up to 3400Hz for clear tones
• Large piezo capacitance uses 70000pF to shape drive response
• Low-voltage operation accepts 2V to 30V for flexible supply choices
• Minimal supply draw consumes 8mA to reduce system load
• Tin-plated termination improves solderability and connection integrity

• Suitable for alarm and warning circuits in industrial controllers
• Ideal for machine status indication on production lines
• Used for audible prompts in automation and test rigs
• Can be used for retrofit signalling in electrical cabinets

It is designed for through-hole mounting, so PCB hole patterns and soldering processes must accommodate a through-hole component.

It maintains functionality between -30°C and 105°C, allowing use where cycles or elevated ambient temperatures occur.

It requires an external drive and accepts supply voltages from 2V to 30V, drive circuitry should match the specified capacitance and current profile.

Termination is tin-plated on red copper, which supports standard soldering techniques and reliable electrical joints.

The component meets REACH and RoHS standards, aligning with common material-restriction requirements in equipment manufacturing.
