霍爾效應(yīng)非接觸傳感

　　本文討論了霍爾效應(yīng)傳感器的工作原理，以及線(xiàn)性和開(kāi)關(guān)霍爾效應(yīng)傳感器在工業(yè)自動(dòng)化中的應(yīng)用。它著眼于技術(shù)的最新發(fā)展，以及將這些傳感器集成到諸如電流傳感和電機(jī)控制等應(yīng)用的工業(yè)設(shè)備的最佳技術(shù)。

　　它包括設(shè)備如A1324從快板和AD22151使用從電機(jī)控制開(kāi)關(guān)應(yīng)用的模擬裝置，以及磁阻電流傳感器從霍尼韋爾hmc1052家庭。從AMS的as5510如何增加層次的整合可以進(jìn)一步降低基于驅(qū)動(dòng)器的設(shè)計(jì)的復(fù)雜性，使用霍爾效應(yīng)傳感器。

　　Contactless sensing with the Hall Effect

　　Contactless sensing through the Hall Effect is becoming a key technology for motor control and appliances. The effect provides a low-cost combination of both sensing and switching that simplifies the cost and implementation of a design， but can also open up new design opportunities. For example， using the magnetic-sensing capabilities and integrating orthogonal Hall sensors can produce an effective low-cost compass.
