Materials for sensor applications
SONOX® P5, SONOX® P502, SONOX® P504, SONOX® P508, PZT 503, PZT5A1, PZT 5A4, PZT5H1
- Permittivity in between 1000 and 2000
- High piezoelectric activity (d33 ≥ 400 * 10-12 C/N)
- Low mechanical quality factor (≤100)
Sensor applications are mainly combined systems in which the piezoceramic is used as ultrasonic-transmitter on the one hand and as a receiver on the other hand. SONOX® P502 and SONOX® P504 are specially developed materials with a high rate of thermal and temporal stability. For this reason, they are very suitable for automotive applications in the area ranging from –40 to +160º Celsius.
