Oversea specification

Important notes on selection

(1) The value shown for load capacity in "Main specification" refers to the maximum value. When enabling the power saving setting, the main specifications will change. For details, refer to "Payload table by speed/acceleration".
(2) Horizontal load capacity shown assumes an operation running with an external guide. Detent mechanism may get damaged if a force was applied to the rod, except towards its moving direction.
(3) Please refer to "Correlation diagram of pressing force and current limiting value" if you wish to have pressing motions to be carried out. Pressing force shown are their standard value.
(4) It is necessary to limit the duty depending on the ambient temperature used. Refer to page 1-280 for further details.
(5) The interface box is not dust-proof and drip-proof. Install it in a place where it will not be exposed to water.
(6) Safety measures may be required depending on the attachment orientation. Refer to page 1-261 for further details.

S.E.: Stroke end

*1 Actuator cable length can be changed to 5m as an option.

*2 The interface box relay section inside the broken line is not dust-proof and drip-proof.

*3 Select the actuator cable and power I/O cable so to have their total length 10m or less.

(Note) The rod moves to the M.E. upon returning to origin, so please take precaution that it may not interfere with anything while the returning process is running.
