ND18X2N21

ND18X2N21 is a ND series disc shape piezoelectric transducer. It is a disc shaped piezoceramics that use original high-performance piezoelectric materials. This product is based on the principle of the piezoelectric effect that generates a charge in response to pressure and an inverse piezoelectric effect that generates strain in response to voltage. Typical applications include vibratory feeder, ultrasonic cleaning machine, ultrasonic levitation, ultrasonic flow and level meter, ultrasonic distance sensor and load sensor, impact sensor.

• N21 material has high coupling coefficient and a large g-constant, suitable for sensing applications
• Ceramic outer diameter is φ18mm
• 0.078inch thickness
• Operating temperature range from −20°C to +60°C
