编码器注意三方面的参数：
1、械安装尺寸：包括定位止口，轴径，安装孔位;电缆出线方式;安装空间体积;工作环境护等级是否满足要求。
2、分辨率：即编码器工作时每圈输出的脉冲数，是否满足设计使用要求。
3、电气接口：编码器输出方式常见有推拉输出(F型HTL格式)，电压输出(E)，集电开路(C，常见C为NPN型管输出，C2为PNP型 管输出)，长线驱动器输出。其输出方式应和其控制系统的接口电路相匹配。[2]

光电编码器
优点：体积小，精密，本身分辨度可以很高，无接触无磨损;同一品种既可检测角度位移，又可在机械转换装置帮助下检测直线 位移;多圈光电编码器可以检测相当长量程的直线位移(如25位多圈)。寿命长，安装随意，接口形式丰富，价格合理。成熟 技术，多年前已在国内外得到广泛应用。[3]
缺点：精密但对户外及恶劣环境下使用提出较高的保护要求；量测直线位移需依赖机械装置转换，需消除机械间隙带来的误差； 检测轨道运行物体克服滑差。
