Murata develops world’s first surface mount ultrasonic sensor

Murata today announced that it has developed a surface-mount device (SMD) -type ultrasonic sensor. Through the use of an exclusive structural design, including the ceramic element, Murata succeeded in developing the world’s first surface-mount device (SMD) -type ultrasonic sensor. Since it is a surface-mount device (SMD) , the new sensor requires minimal mounting space, and it enables improved functionality for distance measurement and position detection through the use of ultrasonic waves.

Constructed in an ultra low profile package measuring just 5.2 × 5.2mm and 1.15mm thick, the MA40H1S-R series is capable of delivering up to 100 dB sound pressure at 40kHz. Operating voltage is 6 Vp-p and the sensor has a -6dB full angle beam of 80 degrees. Typical applications include distance measurement, position detection and 3D gesture detection in portable equipment.
