Semiconductor magnetic sensors are on track to attain 7 percent revenue growth this year, due to widespread adoption in the automotive sector, according to a new report from IHS. Global market revenue for magnetic sensors will reach $1.73 billion at year-end, up from $1.62 billion in 2012. Next year will see revenue expand again by approximately 7 percent to reach $1.85 billion, with growth continuing during the following three years ranging from 4 to 8 percent. By 2017, industry takings will amount to some $2.20 billion. Magnetic sensors are used to track rotational speed and linear angles in machines and devices, or to detect and process magnetic fields to establish positioning.
