Piezoelectric element for automotive backup sensors
Generate ultrasonic signals for necessary distance measurements! It provides high sensitivity and high sound pressure with excellent durability and reliability.
The backup sensor is one application of ultrasonic transducers in the air. It generates ultrasonic signals necessary for distance measurement in automotive backup sensors. It transmits ultrasonic signals using piezoelectric ceramic transducers and receives echoes. The distance to an obstacle is obtained by calculating the time lag between the transmitted signal and the received signal. 【Features】 ■ High sound pressure ■ Excellent durability and reliability ■ High sensitivity ■ Low temperature coefficient *For more details, please refer to the PDF document or feel free to contact us.
