Murata has developed a surface-mount device (SMD)-type ultrasonic sensor whose production starts in summer 2014. It is designed for applications like distance measurement, position detection and 3D gesture detection in portable equipment. Distributor Rutronik presented the new sensors at the Sensor + Test exhibition from June 3 to 5, 2014 inNuremberg.

Constructed in an ultra low profile package measuring only 5.2 x 5.2 x 1.15mm, the MA40H1S-R series of SMD ultrasonic sensors is capable of delivering up to 100dB sound pressure at 40kHz. Its operating voltage is 6Vp-p. The sensor comes with a -6dB full angle beam of 80 degrees.

Utilising an exclusive structural design, including the ceramic element, Murata Manufacturing managed to develop world’s first SMD-type ultrasonic sensor. It requires minimal mounting space and enables improved functionality for distance measurement and position detection through the use of ultrasonic waves.
