　　为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。电缆的屏蔽要求是根据不同场合分别采用：对绞组合屏蔽、对绞组成电缆的总屏蔽、对绞组合屏蔽后总屏蔽等方法。屏蔽材料有圆铜线，铜带、铝带/塑料复合带三种。

严格来讲，编码器只会告诉你改如何定位，要如何执行，是需要靠数控系统（或者plc之类控制器）控制伺服或者步进电机来实现定位的，编码器好比人的眼睛，知道电机轴或者负载处于当前某个位置，工业上用的一般是光电类型编码器，下边简单说明一下。简单说下编码原理和位置测量光电编码器是在一个很薄很轻的圆盘子上，通过紧密仪器来腐蚀雕刻了很多条细小的缝，相当于把一个360度，细分成很多等分，比如成1024组，这样每组之间的角度差是360/1024度=0.3515625度。
