The TH Series has been upgraded to the TH-A Series of Scara Robots. Standard cycle times are 0.31 sec with a 2-kg payload for the TH650A, and 0.39 sec with a 5-kg payload for the TH850A and the TH1050A. X-, Y- and Z-Axis positioning repeatability for all three models is ± 0.01-mm., while C-Axis positioning repeatability is ± 0.004-deg. The rigid construction and vibration-free performance of the robot series results in a longer robot life, the co. states. The TH-A Series features a sealed labyrinth structure as standard. Piping positions are flexible, and may easily be changed by the end user. Because two harnesses are in the robot arm, it is easy to replace them. Other features of the robot series include lower profiles, reduced noise levels and easy maintenance.
