Note1) Strokes other than the above are produced as a special order.
Note2) Details are shown in
“Speed-Work load graph (indication)” of catalogue.
Note3) The allowable speed will be affected by the stroke length.
Note4) A reference value for correcting an error in reciprocal operation.
Note5) Impact resistance: No malfunction occurred when the actuator was tested with a drop
tester. In both axial and perpendicular direction to the lead screw (the test was
performed with the actuator in the initial state).
Vibration resistance: No malfunction occurred in a test ranging between 45 to 2000 Hz,
when the actuator was tested in both an axial and perpendicular direction to the lead
screw. (The test was performed with the actuator in the initial state.)
Note6) Only applies to actuators supplied with lock.
Note7) For the actuator with lock, please add the power consumption for the lock.
Note8) Sensor magnet position is located at the centre of the table.
Note9) Do not allow collisions at either end of the table travel range.
In addition, when running the positioning operation, do not set within 2 mm of either end.
Note10) Consult with SMC for the manufacture of intermediate strokes.
(Manufacturable stroke range LEJS40/200 up to 1200mm, LEJS63/300 up to 1500mm,
