• The maximum work load at 3000mm/s2. Speed changes according to the controller/driver type and work load. Check the “Speed-Work Load Graph (Guide) in the WEB catalog. Furthermore, if the cable length exceeds 5m, then it will decrease  by up to 10% for each 5m.

• A reference value for correcting an error in reciprocal operation.

• Impact resistance: No malfunction occurred when the actuator was tested with a drop tester in both an axial direction 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  direction and a perpendicular direction to the lead screw. (The test was performed with the actuator in the initial state.)

•  Static allowable moment is the static moment applied to the actuator stopped. If an impact is applied or a repeated load is applied,
  ensure sufficient safety before use.

•  Indicates the max. power during operation.(including the controller) This value can be used for the selection of the power supply. Note 7) With lock only

• For an actuator with lock, add the power consumption for the lock.

 How to order the product

Note: Please consult with SMC for non-standard strokes as they are produced as special orders.

• Excluding LEFS16
• If 2 or more are required, please order them separately. (Part no. LEF-D-2-1 For details, refer to the Web Catalog,)
• Order auto switches separately. (For details, refer to the Web Catalog.)
•  When “Nil” is selected, the product will not come with a built-in magnet for an auto switch, and so a mounting bracket cannot be secured. Be sure to select an appropriate model initially as the product cannot be changed to have auto switch compatibility after purchase.
•  For details on the mounting method, refer to the Web Catalog.
•  Produced upon receipt of order
•  The DIN rail is not included. Order it separately.
• Select “Nil” for anything other than Device Net TM, CC-Link, or parallel input. Select “Nil”, “S”, or “T” for Device Net TM or CC-Link.

Select “Nil”, “1”, “3”, or “5” for parallel input.

Caution
Actuator and controller are sold as a set. When purchasing without controller, make sure that the combination of actuator and controller is correct.
