Murata claims first for surface mount ultrasonic sensor

Available in an ultra low profile package measuring 5.2 x 5.2 x 1.15mm, the MA40H1S-R is capable of delivering up to 100dB sound pressure at 40kHz. Operating voltage is rated at 6Vp-p and the sensor has a -6dB full angle beam of 80°. Because it is a surface mount device, the MA40H1S-R requires minimal mounting space. What's more, Murata says it enables improved functionality for distance measurement and position detection through the use of ultrasonic waves. Typical applications include distance measurement, position detection and 3D gesture detection in portable equipment.
