17mm Passive PCB-Mounting Piezo Buzzer: High-Fidelity Acoustic Feedback by Pran Electronics Pvt. Ltd.
When your application requires a louder, more robust acoustic signal than standard miniature sounders can provide, the 17mm Passive PCB-Mounting Piezo Buzzer from Pran Electronics Pvt. Ltd. is the engineered solution. Designed and manufactured in India, this high-performance transducer is the gold standard for industrial alarms, automotive alerts, and high-end consumer appliances.
Product Overview: Power and Precision in a 17mm Frame
The 17mm series is a significant step up in acoustic resonance. By increasing the diaphragm surface area, this passive buzzer delivers a richer sound profile and higher decibel output at lower frequencies compared to smaller 12mm models.
As a Passive Transducer, it functions as a high-impedance capacitive load. It requires an external drive circuit (square wave or PWM signal) to vibrate the ceramic element, giving design engineers the flexibility to create custom melodies, varying beep patterns, and multi-frequency alerts.
-
Expanded Acoustic Chamber: The 17mm diameter allows for a larger internal air column, resulting in superior sound projection.
-
Low Power, High Output: Achieves high Sound Pressure Levels (SPL) while drawing minimal current—perfect for green-energy designs.
-
Pin-Mount Stability: Rugged through-hole pins ensure the component remains secure even in high-vibration environments.

Why Choose the 17mm Pran Piezo Buzzer?
1. Superior Industrial Durability
Our 17mm buzzers are encased in high-temperature resistant PBT (Polybutylene Terephthalate) housing. This material is chosen for its excellent dimensional stability during wave soldering and its ability to withstand harsh industrial chemicals and heat.
2. Custom Frequency Tuning
Because this is a passive component, you are not locked into a single “factory” tone. By adjusting the input frequency (typically between 2 to 4 K Hz, you can find the “sweet spot” of your specific enclosure to maximize volume and clarity.
3. Certified “Make in India” Excellence
Produced at our ISO 9001:2015 certified Vadodara plant, every unit is RoHS compliant. We utilize precision silver-electrode ceramic discs to ensure long-term stability and prevent “fading” of sound over the product’s lifespan.
Common Applications
-
Automotive Systems: Reverse parking sensors, seat belt reminders, and turn signal indicators.
-
Industrial Automation: Control panel alerts, PLC error codes, and heavy-machinery safety warnings.
-
Consumer Appliances: High-end washing machines, microwave ovens, and air conditioners.
-
Medical Devices: Patient monitoring equipment and infusion pump alarms.
-
Security & Fire: Smoke detector secondary sounders and intruder alarm panels.
The Pran Electronics Advantage
With over 25 years of specialized experience in electro-mechanical components, Pran Electronics Pvt. Ltd. provides more than just a part—we provide a partnership. We offer bulk customization for pin lengths and frequency optimization to suit your specific PCB layout.
Engineering Note: For maximum efficiency, we recommend driving the 17mm buzzer at its Resonant Frequency using a push-pull circuit or a transistor-driven PWM signal from your micro controller.
