产品介绍

简单介绍:

     绝对值磁性尺SR74/SR75:为工作机械所开发的最适合用在精密平台定位的磁尺,输出信号为增量式A/B相/原点差动信号(符合EIA-422)及增量式串列双方向信号(符合EIA-485);适用工控系统:FANUC、三菱电机、松下性:

产品特性:

适合应用于精密平台定位
  薄型增量型磁尺
  该系列磁性尺是永久磁性记录组成,所以即使暴露在冷却液下,也可以不受其影响,能保持读取能力。且因该系列尺与本体以铁制成,故温度膨胀系数与机台相同,精密度不易失真,且抗振动与冲击。

 

      SR74  SR75 多原点磁尺:为工作机械所开发的最适合用在精密平台定位的磁尺,输出信号为增量式A/B相/原点差动信号(符合EIA-422)及增量式串列双方向信号(符合EIA-485);精度(3+3ML/1000)μm,测量长度:70-2040mm,分辨率0.01µm,响应速度:200m/min,适用工控系统:FANUC、三菱电机、松下
