产品介绍

简单介绍：

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。
