This 27mm Piezoelectric Ceramic Buzzer is a highly efficient, slim-profile component designed to provide clear audible alerts or sense vibrations in electronic projects. Operating on the piezoelectric effect, it generates sound through the mechanical deformation of a ceramic disk when an oscillating voltage is applied.
Key Features
• Clear Sound Output: Produces a high-frequency, piercing tone that is easily audible even in noisy environments.
• Ultra-Thin Profile: The flat, lightweight design allows for seamless integration into compact enclosures or surface-mount applications.
• Low Power Consumption: Extremely energy-efficient, making it ideal for battery-operated devices and low-power microcontrollers.
• Versatile Functionality: While primarily used as an acoustic transducer (buzzer), it can also function as a highly sensitive vibration or knock sensor.
Technical Specifications
• Diameter: 27mm
• Resonant Frequency: Typically 4.0 pm 0.5 text{ kHz}
• Resonant Resistance: 300 Omega (maximum)
• Capacitance: 20,000 text{ pF} pm 30% at 100 text{ Hz}
• Operating Temperature: -20^circtext{C} to +70^circtext{C}
Common Applications
• Audible Feedback: Perfect for user interface “beeps” in household appliances, security systems, and timers.
• Condition Monitoring: Used in predictive maintenance to detect mechanical vibrations or impacts.
• DIY Electronics: A staple for alarm circuits, metronomes, and musical greeting cards.
• Robotics & IoT: Ideal for providing status alerts or serving as a collision sensor in autonomous systems.
