Magnetic sensor revenue to rise by 6% this year

According to the latest forecast from IHS, semiconductor magnetic sensors will log seven per cent revenue growth this year due to widespread adoption in the automotive sector. 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 nearly seven per cent to reach $1.85 billion, with continued growth during the following three years ranging from 4-8 per cent. By 2017, industry takings will amount to some $2.20 billion, added the market research company.

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.

"More than five billion magnetic sensors and switches were sold last year, with automotive accounting for 52 per cent of revenue and the consumer and mobile sector making up another 37 per cent," said Richard Dixon, principal analyst for MEMS and sensors at IHS. "The rest was in industry, energy, medical and other smaller applications, such as the transport, aerospace and maritime sectors."

In the past the sensors enjoyed a remarkable run of growth, helped to some degree by their key role in vehicle safety systems required by mandates. For instance, electronic stability control (ESC) systems engineered to help prevent vehicle skidding were a potent driving force in consumption, given the use of relatively expensive steering-wheel-angle sensors and at least four wheel-speed sensors.

ESC mandates helped propel the sensors towards rapid growth during the last several years, especially as they were being enforced in the highly developed automotive markets of the United States, Canada, the European Union, Australia, South Korea and Japan.

Overall, Hall-type IC sensors and switches remain the most prominent magnetic sensor device, making up a whopping 89 per cent of market revenue in 2012. Applications for Hall sensors include wheel-speed sensing in anti-lock brake systems; acceleration pedals; electronic throttle valve position; crankshaft sensing; and exhaust gas recirculation. In addition, there are as many as 30 applications for simple switches in the body of the vehicleHall-effect sensors dominate in this low-cost switch category.
