SMC 11-LEFS40A-650B | Clean Room Electric Actuator LEFS Series Ball Screw Drive 40mm Width 650mm Stroke Step/Servo Motor 24VDC High Capacity
SMCThe SMC 11-LEFS40A-650B is a clean room specification electric actuator from the LEFS series with ball screw drive and the largest 40mm width body. Part number decoded: LEFS = LEFS series ball screw electric actuator, 40 = 40mm width (largest body in the LEFS range), A = A-type step motor servo 24VDC, 650 = 650mm stroke, B = additional specification. The 40mm width delivers maximum payload capacity and moment load resistance in the LEFS platform.
The 40mm width provides the widest bearing separation, enabling the heaviest payloads and longest moment arms in the LEFS family. Combined with 650mm stroke, this actuator handles heavy clean room material transfer, large fixture positioning, and extended-range operations with substantial end-effector weight. The A-type step motor servo at 24VDC provides reliable multi-point positioning with the ball screw's precision and thrust force, suited for applications where payload capacity is more important than maximum speed.
The LEFS40A-650B is the high-capacity long-stroke option in the LEFS range. For the same 40mm width at shorter strokes, options include 150mm and 200mm. For the LEFG slider comparison at 40mm width, the LEFG40-S-400 provides 400mm travel with belt or rod drive. For AC servo motor performance at 40mm width, specify the S3A motor type if available. For even higher payload capacity beyond the LEFS40, consult SMC for LEY rod-type or custom actuator solutions. Requires compatible controller. Clean series (11-). RoHS compliant.
