Infineon prospers in automotive magnetic sensor ranking

Market news |
By Peter Clarke

The increased popularity of magnetoresisitive (MR) sensors for safety-critical applications will contribute to this. MR sensors can be more accurate than Hall-effect or inductive-based sensors but are typically more expensive.

There are more than 60 magnetic sensor applications, on average, in cars sold in Europe, Japan, North America and other markets such as China. The major sensing applications include steering, braking, acceleration pedal and electronic throttle systems.

Most magnetic sensor companies posted strong growth in 2016 thanks to their leading position in supplying sensors for steering systems and other safety-critical applications. A typical steering system includes two angle sensors, two torque sensors and even steering-motor-control sensors. As a result of this focus, Infineon, Allegro Microsystems, Melexis, Micronas and NXP control 90 percent of the market for magnetic sensors.
