OUTLINE
The piezoelectrical effect of piezoelectric ceramic is used in this ultrasonic sensor for detecting the 40kHz- wavelength of acoustic energy.
FEATURES
1. Small size, light weight.
2. Size can be between ø15 ~ 20mm in diameter.
3. Optimum structure and decay time.
4. Maximum input voltage is large, and sensitivity setting is easy.
5. Wide usage temperature range: -30 ~ +80°C
6. Sensor is sealed and suitable for in-vehicle or outdoor use.
USES
1. Car rear sensors (sonar)
2. Unattended parking systems
3. Unattended open/close systems
4. Intruder warning devices
