Piezo Electric Sensor Buzzer 27mm Without Soldering

The Piezo Electric Sensor Buzzer 27mm produces a tone output at 10kHz ±0.5kHz frequency with 85dB sound pressure level, operating across -20°C to 70°C, with a 27mm body that mounts without any soldering required. While the name includes “sensor,” this piezo buzzer works in the opposite direction from a piezo sensing element — instead of generating voltage from mechanical stress, applying an oscillating electrical signal to its piezo disc causes it to vibrate mechanically, producing the audible tone.

The piezo buzzer price reflects a solder-free design using spring-clip or connector-style terminals rather than bare wire leads, making the piezoelectric sensor buzzer quick to wire into a breadboard or terminal block without needing a soldering iron, which most comparable piezo buzzer elements require. This unsoldered piezo buzzer’s fixed 10kHz tone frequency makes it suitable for simple alert and alarm applications rather than projects needing variable musical tones across a wide frequency range.
