（2）轴套型：轴套型又可分为半空型、全空型和大口径型等。
4、以编码器工作原理可分为：光电式、磁电式和触点电刷式。
常见故障
1、编码器本身故障：是指编码器本身元器件出现故障，
其不能产生和输出正确的波形。这种情况下需更换编码器或其内部器件。
2、编码器连接电缆故障：这种故障出现的几率 高，中经常遇到，应是优先考虑的因素。通常为编码器电缆断路、短路或不良，这时需更换电缆或接头。还应特别注意是否是由于电缆固定不紧，造成松动引起开焊或断路，这时需卡紧电缆。
3、编码器+5V电源下降：是指+5V电源过低， 通常不能低于4.75V，造成过低的原因是供电电源故障或电源传送电缆阻值偏大而引起损耗，这时需检修电源或更换电缆。
4、式编码器电池电压下降：这种故障通常有含义明确的，
这时需更换电池，如果参考点位置记忆丢失，还须执行重回参考点操作。
5、编码器电缆屏蔽线未接或脱落：这会引入，使波形不，影响通信的准确性，必须保证屏蔽线可靠的焊接及接地。
6、编码器安装松动：这种故障会影响位置控制 精度，造成停止和中位置偏差量超差，甚至刚一开机即产生伺服过载，请特别注意。
7、光栅污染 这会使输出幅度下降，必须用脱脂棉沾无水酒精轻轻擦除油污。
安装使用
型编码器的机械安装使用：
型编码器的机械安装有高速端安装、低速端安装、
辅助机械装置安装等多种形式。
高速端安装：安装于动力马达转轴端（或齿轮连接），此优点是分辨率高，由于多圈编码器有4096圈，马达转动圈数在此量程范围内，可充分用足量程而分辨率，缺点是运动物体通过减速齿轮后，来回程有齿轮间隙误差，一般用于单向高精度控制定位，例如轧钢的辊缝控制。另外编码器直接安装于高速端，马达抖动须较小，不然易损坏编码器。
低速端安装：安装于减速齿轮后，如卷扬钢丝绳卷筒的轴端或后一节减速齿轮轴端，此已无齿轮来回程间隙，测量较直接，精度较高，此一般测量长距离定位，例如各种设备，送料小车定位等。
辅助机械安装：
常用的有齿轮齿条、链条皮带、转轮、收绳机械等。
接线
编码器是一种光电式测量装置，它将被测的角位移直接转换成数字（高速脉冲）。
