This piezo-ceramic transducers have dual functions transmitters and receivers with high signal/noise ratio (S/N) and very short ring time. Such components are specially designed for auto back sonar. Its close type structure can prevent from weather damage. Ultrasonic sensor selection chart for the code of standard model number.
