Our drip-proof ultrasonic sensors are constructed by pasting piezoelectric ceramics to a metal case and then filling the opening of that case with resin. This structure protects against water droplets and dust, which become a problem when used outdoors. We have enabled stable short-distance and long-distance detection performance with our MA48CF15-7N sensors by tightening the tolerance of the sensor characteristics compared to conventional products. These products are suitable for applications such as automatic braking systems and automatic parking systems in automobiles due to their high reliability together with their stable distance detection performance.
