When your electronic design demands a high-intensity, attention-grabbing audio signal, the 22mm Passive PCB-Mounting Piezo Buzzer from Pran Electronics Pvt. Ltd. is the ultimate solution. Engineered for maximum resonance and industrial-grade durability, this 22mm transducer is the largest in our standard PCB-mount range, offering unparalleled sound pressure levels (SPL) for critical alert systems.
Product Overview: The Powerhouse of Piezo Sounders
The 22mm diameter series is specifically designed for applications where ambient noise is high or where the alert must be heard from a significant distance. By utilizing a larger ceramic disc and an optimized internal acoustic chamber, this buzzer produces a deep, penetrating tone that smaller sounders simply cannot match.
As a Passive Transducer, it requires an external drive signal (typically a square wave). This allows for sophisticated sound design, enabling the buzzer to emit everything from a soft “chirp” to a high-decibel “siren” effect depending on the input frequency.
- Superior Sound Projection: The large 22mm diaphragm moves more air, resulting in a louder, more authoritative acoustic output.
- Low Current, High Efficiency: Even at its highest volume, the piezo technology ensures minimal power draw, making it ideal for battery-backed security systems.
- Rugged Through-Hole Design: Features reinforced pins for secure mounting on PCBs subject to high vibration or mechanical stress.
