Applications Reversing detection - Assisted parking system -Blind spot information systemSpecial use for medical equipment ultrasonic sensor
With perfect seal these sensors can be used in a relatively poor environment such as dust and humidity.
The ultrasonic transducer utilizes piezoelectric effect to convert electricity to mechanical vibration and form ultrasonic waves. Therefore no coil is contained and electromagnetic interference can be greatly reduced. The ultrasonic wave has excellent directivity and strong penetrability, and is interfered by neither the dust and electromagnetic fields in the air, nor the color and temperature at object surfaces.
