一、无触点限位开关在各种机床和生产线的自动控制中,机械设备的有关部件和工件要进行准确的相对运动。任何一个部件的相对运动,如在x、y、z三个坐标上的位移和转动(即六个自由度)都必须按一定的规律进行,也就是 First, the non-contact limit switch Automatic control of various machine tools and production lines, machinery and equipment related parts and components to carry out accurate relative motion. The relative motion of any one component, such as the displacement and rotation (ie, six degrees of freedom) in the three coordinates of x, y and z must be carried out according to a certain rule, that is,
