Ultrasonic sensors


Ultrasonic sensors emit ultrasonic waves in the air that reflect off of objects. The reflected sound is then received by the sensor.

This technology is used for detection of objects in burglar alarms and automatic doors as well as for range measurement in automotive parking assistance systems.

The sustained development of unique piezoelectric ceramic technology at Murata over the years has allowed the company to commercialize a diverse lineup of compact high- performance aerial ultrasonic sensors.
