的材料和加工水平、以及结构合理性提出了挑战，因此基于CDH2型技术开发的这类产品满足了现代轧机高性能的要求。,38,14th15thJanuary2004,BoschRexrothinChina,HydrauliccylindersBRI-ZYProximityswitch接近开关,39,14th15thJanuary2004,BoschRexrothinChina,Function功能:Output输出(PNP)Operatingvoltage工作电压:10.30VDCincludingtheresidualripple15%包括残余波动Ratedoperatingcurrent额定工作电流:24VDC,Repeatability重复性:5%Hysteresis滞后:15%Ambienttemperaturerange环境温度范围:-20.+80C,HydrauliccylindersBRI-ZYEndpositioncontrol终端位置控制,40,14th15thJanuary2004,BoschRexrothinChina,Positionsensing位置测量Limitswitchfunctions终端开关功能Closedloopcontrols闭环控制,HydrauliccylindersBRI-ZYIntegrateddisplacementtransducer内置式位置传感器,41,14th15thJanuary2004,BoschRexrothinChina,Analogoutput模拟量输出:0to10VLoadresistance负载阻力:5KResolution分辨能力:infinite
