With thousands of electronic components available in the market, it just seems too complicated and cumbersome. We strive to make electronics easier, accessible, clutter-free for Novices and Advanced users. You could be an advanced user like a professional lab engineer, electronic major student, experienced hobbyists, or a novice user who doesn't have much electronics knowledge. Fear not, we got you both covered. As our tagline suggests - "The Last Piece of the Puzzle or Maybe the First" Specifications Resonance Frequency: 4.6 Khz +/- 0.5 Khzv Resonance Impedance: 200 Ohms Capacitance: 20nF +/- 30% at 1 Khz Operating Temperature -20...+70 C Storage Temperature -30...+80 C 27 MM Piezo Ceramic Elements Sounder Sensor Trigger Drum Disc + Wire Copper Piezoelectric Buzzer Copper 27mm - PACK OF 20 Description A piezoelectric sensor/element is a device that uses the piezoelectric effect, it is basically a device which converts voltage to vibration and vibration to voltage. It normally comes in handy to measure knock (knock sensor) or vibration (vibration sensor). Now a days it is also used extensively in power generation projects e.g. Foot Step Power Generation.
