$1,660.00
The SMC 11-LEFS40B-400 is a clean room specification electric actuator from the LEFS series with B-type motor and the largest 40mm width body at 400mm stroke. Part number decoded: LEFS = LEFS series ball screw electric actuator, 40 = 40mm width, B = B-type servo motor, 400 = 400mm stroke. This provides medium-long travel with maximum payload capacity in the LEFS platform.
The 400mm stroke at 40mm width provides a versatile configuration for heavy-duty clean room positioning. The B-type servo motor delivers continuous torque for sustained motion and precise speed control throughout the 400mm travel. Applications include heavy assembly transfer between stations, large fixture repositioning, extended-range dispensing operations with heavy dispensing heads, and programmable scanning of wide substrates in inspection and metrology equipment.
The LEFS40B-400 sits in the mid-range of LEFS40 stroke options. For shorter travel, the LEFS40B-150 and LEFS40B-150B provide compact configurations. For longer strokes, the LEFS40B-600B and LEFS40B-700B extend to 600mm and 700mm respectively. For A-type motor at 40mm width and similar stroke, the LEFS40A-650B provides step motor servo operation. For high-precision variants, the LEFSH series adds enhanced guide rigidity. Requires compatible B-type motor controller. Clean series (11-). RoHS compliant.
