SCB pneumatic control module, as a special control module for soft clamps, can output the safe gas pressure that soft clamps can tolerate, which can not be filled by the conventional industrial gas source. The gas pressure inside the grippers can be adjusted through the control module to realize the precise control of the gripping of the soft clamps. Among them, the SCB-PBS protective pneumatic control module features a high protection level, which is suitable for working in harsh environments such as dust, oil, humidity, and so on.
