Oversea specification
Important notes on selection
 | (1) The maximum opening/closing speed of the "Main specification" indicates the operating speed of one side. The relative operating speed will be the double. (2) The maximum gripping force of the "Main specification" is the total value of the gripping force of both fingers when the gripping point distance and the overhang distance is 0. For the actual work mass that can be transported, refer to "Checking the Gripping Point Distance". (3) Be sure to use push-motion operation to grip the work. (4) Self-locking feature maintains the work gripping force even when the power is cut off. In order to remove the work being gripped when the power is turned off, turn the opening/closing screw on the side or remove the finger attachment to remove the work. |
Dimension drawing
S.E.: Stroke end
※1 Plugged with a set screw to prevent foreign matter from entering. Remove it before using mounting surface A.
(Note) Home position is at the open side as standard. To have the home position positioned on the closed side, please specify from the option (Model: NM).

Checking the Gripping Point Distance
When using, make sure that the distance (L, H) from the finger (claw) mounting surface to the gripping point is within the range of the graph.
(Note) If the limit range is exceeded, an excessive moment will be applied to the finger sliding part and the internal mechanism, which may adversely affect the service life.
Gripping Force
■Correlation Diagram of Gripping Force and Current Limit Value
(Note) The total value of both fingers when the gripping point distance (L, H) is 0.
(Note) Values indicated are for reference only. There is a variation of about 0 to 60%. The possibility of variation increases especially when the current limit value outside the recommended area (coloured area in the graph) is set.
(Note) The speed is fixed at 5mm/s for gripping (pushing) motion.
■Reference for Gripping Point Distance and Gripping Force
(Note) The value indicates the gripping force depending on the overhang position when the maximum gripping force is 100%. Results may vary depending on the rigidity of the finger attachment used.
