　　磁传感器：越来越多的使用，尺寸的缩小

　　磁传感器传统上用于汽车、工业和消费应用中的速度、转速、线性位置、线性角度和位置测量。特别是，汽车行业已成为全球市场领导者的磁场传感器，会计，并根据一些估计，超过百分之40的总磁场传感器市场。不断增长的需求，在汽车上集成更多的安全功能，创造了磁场传感器的机会，这是用在各种安全应用，如电子稳定控制（ESC）系统、转向角传感器、力和力矩传感和防抱死制动系统（ABS），其中。

　　还有一个在消费电子市场的磁传感器电子罗盘相关的高增长率（或e-compasses）已成为流行的主要原因是他们提高消费电子设备的用户的导航体验的能力。

　　据市场研究公司iSuppli，硅磁传感器的全球收入将达到2017美元，已经运行在108亿的复合年均增长率（CAGR）约百分之12。

　　Over the past two decades， the use of magnetic sensors has blossomed based on the lower cost and higher quality of Hall Effect and magnetoresistive （MR） sensors. Hall-Effect solutions are popular because they outperform potentiometers， reed sensors， and mechanical switches at higher performance levels thanks to their robustness and the elimination of mechanical wear， a common source of premature failure. MR sensors feature inherently low hysteresis and high linearity for improved measurement accuracy. （As the magnet moves closer to the magnetic-field sensor， the value becomes high enough for the circuitry and the output is turned on. As the magnet is moved away from the sensor the field is weakened and the output is turned off. Hysteresis is the differential between when the output is turned on and when the output is switched off.）
