Gripper fingers are fastened to the gripper jaws. The payload can be gripped in 2 ways: – on the external contour (external gripping) when closing – on the internal contour (internal gripping) when opening The parallel gripper is controlled by a higher-order controller using digital signals. 5.2 Structure 1 2 4 5 3 6 7 8 9 Fig. 1: Product design 1 Gripper jaw 2 Slot for proximity switch 3 Rotary switch for setting the speed for gripping force 4 Locating hole and thread for mounting 5 Electrical connection 6 LED Ready 7 LED Error 8 Plug screw 9 Locating hole and thread for gripper finger mounting 6 Transport and storage – Store the product in a cool, dry environment protected from UV and corrosion.
