This Absolute encoder XCC series can be used for optical reading and has a high resistance to dirt, temperature and deterioration. Incremental and absolute encoders vary in housing diameters (40, 58, 90mm), shaft types (modular solid, reduction collars), and resolution (100 to 80 000 points). Meanwhile, communicating absolute multiturn encoders have the same shaft types with that of absolute and incremental, but has housing diameter of 58 mm, and a 8192 points/4096 turns resolution which can be used for reading position and speed with CANopen or PROFIBUS-DP communication interface. Absolute single turn encoders can be used for reading position within a revolution while multiturn encoders have the same but with indication of the revolution count.
