HAL202TQ-K数据手册传感器变送器的磁性传感器-开关（固态）规格书PDF

描述 Description

HAL 2xy开关系列产品使用CMOS技术生产。传感器包含主动偏置补偿的温度补偿霍尔片，比较器和开漏输出晶体管。比较器通过霍尔片（霍尔电压）来比较实际的磁通量和设定的参考值（开关点）。相应地，输出晶体管进行开关。主动偏置补偿使得磁参数对机械应力效应下保持稳定可靠。此外，磁参数在全电压和全温度下都是持续的。本系列传感器是为了工业和汽车应用设计的，工作电压从3.8伏到24伏，环境温度从−40 °C up to 125 °C。HAL 2xy产品有SOT89B SMD和铅封 TO92UA两种封装。
