Specifications
Note 1) Consult with SMC for non-standard strokes as they are produced as special orders.
Note 2) Check “Speed–Work Load Graph (Guide)” on page 12.
Note 3) Conforming to JIS B 6191-1999
Note 4) A reference value for correcting an error in reciprocal operation.
Note 5) Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction and a perpendicular direction
to the lead screw. (Test was performed with the actuator in the initial state.)
Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz. Test was performed in both an axial direction and a
perpendicular direction to the lead screw. (Test was performed with the actuator in the initial state.)
Note 6) The power consumption (including the driver) is for when the actuator is operating.
Note 7) The standby power consumption when operating (including the driver) is for when the actuator is stopped in the set position during the operation.
Note 8) The maximum instantaneous power consumption (including the driver) is for when the actuator is operating.
Note 9) Only when motor option “With lock” is selected.
Note 10) For an actuator with lock, add the power consumption for the lock.
Note 11) Sensor magnet position is located in the table center.
For detailed dimensions, refer to “Auto Switch Mounting Position” on page 43.
Note 12) Do not allow collisions at either end of the table traveling distance. Additionally, when running the positioning operation, do not set within 2 mm of
both ends.
Note 13) For “Manufacture of Intermediate Strokes”, please contact SMC.
