Selection considerations
 |
(1) The maximum opening and closing speed in the "Main Specification" indicates the operating speed on one side. The relative operating speed is twice the value. (2) The maximum gripping force in the "Main Specification" is the total value of the gripping force of both fingers when the gripping point distance and overhang distance are 0. For the actual workpiece mass that can be transported, please refer to "Confirming the gripping point distance". (3) When gripping a workpiece , be sure to use the pressing operation. (4) The self-locking mechanism maintains the gripping force even when the power is turned off. (However, it does not guarantee that the workpiece will not be dropped.) When removing a workpiece that is being gripped when the power is turned off, turn the opening and closing screw on the side or remove the finger attachment to remove the workpiece. (5) The duty ratio must be limited depending on the ambient temperature. For details, please refer to page |

SE: Stroke end
(Note) The standard setting is that the open side is the home position. If you wish to set the home position to the closed side, please specify the option (model: NM).
Note: Make sure to secure the cable so that the base of the cable does not move.
(Note) The actuator cable exit direction is standard at the rear, but can be changed to one of four directions as an option.

Check gripping distance
Please use the product so that the distance (L, H) from the finger (claw) mounting surface to the gripping point is within the range shown in the graph.
(Note) If the limit range is exceeded, excessive moment will be applied to the finger sliding part and internal mechanism, which may adversely affect the service life.
Grip Force
■Correlation diagram between gripping force and current limit value
(Note) This is the total value for both fingers when the gripping point distance (L, H) is 0.
(Note) These are approximate values. There is a variation of about 0 to 60%. The possibility of variation is particularly high when the current limit value is set outside the recommended range (the colored range of the graph).
(Note) When gripping (pushing), the speed is fixed at 5 mm/s.
■ Guideline for gripping point distance and gripping force
(Note) The gripping force at the extension position is shown when the maximum gripping force is 100%. The results may vary depending on the rigidity of the finger attachment used.
