Selection considerations
 |
(1) The maximum opening and closing speed in the "main specifications" indicates the operating speed on one side. The relative operating speed is twice the value. (2) The maximum gripping force in the "main specifications" is the total value of the gripping force of both fingers when the gripping point distance is 40 and the overhang distance is 40. 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 cut 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 cut off, turn the opening and closing screw on the side or remove the finger attachment to remove the workpiece. (5) If the waterproof joint cable specification (option model: JYW) is selected, the attached actuator cable will be a waterproof joint cable specification. |
Dimensions
SE: Stroke end
*1 It is plugged with a set screw to prevent foreign matter from getting in. Please remove it when installing the intake and exhaust joint (normally not used).
*2 If the connector connection is subject to vibration or other unstable position, secure the cable with a cable tie or similar to prevent the connector connection from moving.
Make sure to align the arrow printed on the connector and then insert it all the way in.
(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) The actuator cable exit direction is standard at the rear, but can be changed to one of four directions as an option.
(Note) The interface box is not dust-proof or water-proof. Install it in a place where it will not get wet.

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 40.
(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.
