The SMC 11-LEFS40B-150 is a clean room specification electric actuator from the LEFS series with B-type motor and the largest 40mm width body at a short 150mm stroke. Part number decoded: LEFS = LEFS series ball screw electric actuator, 40 = 40mm width, B = B-type servo motor, 150 = 150mm stroke. This creates a maximum-capacity, short-travel precision positioning platform.
The 40mm width with only 150mm stroke provides the highest payload density in the LEFS range maximum load handling in minimum linear travel. This configuration excels in applications where heavy assemblies, large tooling fixtures, or substantial workpiece masses must be precisely positioned over a short distance. Examples include Z-axis press head positioning for heavy bonding tools, short-stroke fixture adjustment for large wafer cassettes, and precision height control of heavy optical inspection heads in clean room equipment.
The LEFS40B-150 provides the shortest LEFS40 travel. For the same width with longer strokes, options extend to 650mm (A-type) and beyond. For A-type motor at 40mm width, the LEFS40A series provides step motor servo alternatives. For the B-motor with additional specification, the LEFS40B-150B adds the B suffix. For the same short stroke at smaller width, the LEFS32B-150B provides 32mm width B-motor operation. Requires compatible B-type controller. Clean series (11-). RoHS compliant.
