Hitachi Metals has announced that it has further expanded its product lineup by developing the world’s smallest-class digital 3-axis accelerometer that generates digital signals.
3-axis accelerometers are used for accidental fall detection in devices that are fitted with mobile hard disk drives, such as music players and notebook computers. They are also used to detect acceleration in navigation and traffic control systems, in sensors for motion measurement and security systems, as well as in a broad range of other applications. Based upon these applications, they are drawing increasing interest in the digital consumer electronics industry.
While leading the industry through its unique micromachine and precision assembly technologies, Hitachi Metals has previously developed 3-axis accelerometers that output analog signals. Recently, based upon customer recognition of their performance and functions, these accelerometers are being increasingly employed for free-fall detection and other applications in devices that are fitted with hard disk drives, and uses are expected to continue expanding. Amidst these circumstances, customer demands are increasing for an accelerometer that outputs digital signals and remains among the world’s smallest. Customers are also expressing a variety of new demands, including calls for greater precision in the measurement of acceleration, and higher performance in free-fall detection.
