SMC 11-LEFS40B-600B | Clean Room Electric Actuator LEFS Series Ball Screw 40mm Width 600mm Stroke B-Motor B-Spec Long Travel
SMCThe SMC 11-LEFS40B-600B is a clean room specification electric actuator from the LEFS series with B-type motor and 600mm long-travel stroke at the maximum 40mm width. Part number decoded: LEFS = LEFS series ball screw electric actuator, 40 = 40mm width, B = B-type servo motor, 600 = 600mm stroke, B = additional specification (brake option or cable configuration).
The 600mm stroke at 40mm width combines extended reach with maximum payload handling. The trailing B specification typically indicates a motor brake for hold-in-place capability when power is removed, essential for inclined or vertical mounting where gravity would otherwise move the slider. For clean room equipment with vertical Z-axis or inclined transfer axes, the brake prevents uncontrolled movement during power interruptions, protecting delicate workpieces and maintaining machine safety.
The LEFS40B-600B provides long-travel heavy-duty positioning with brake capability. For even longer stroke at 40mm width, the LEFS40B-700B extends to 700mm. For the same 600mm without brake, the LEFS40B-600 base unit provides the standard configuration. For A-type motor at similar long stroke, the LEFS40A-650B provides step motor servo operation. For the high-rigidity variant with enhanced guide mechanism, the LEFSH series provides superior moment resistance. Requires compatible B-type motor controller. Clean series (11-). RoHS compliant.
