The SMC 11-LEFS25B-250B-S5 is a clean room specification electric actuator from the LEFS series with B-type motor and S5 controller interface. Part number decoded: LEFS = LEFS series ball screw electric actuator, 25 = 25mm width, B = B-type servo motor, 250 = 250mm stroke, B = additional specification, S5 = controller interface configuration. This is the base B-motor variant at 250mm stroke without the K encoder option found in the LEFS25B-250BK-S5.
The difference between LEFS25B-250B-S5 and LEFS25B-250BK-S5 is the K option. Without K, this actuator uses the standard motor encoder and feedback configuration. The K option adds an enhanced encoder or alternative feedback mechanism. For applications where the standard encoder resolution meets positioning requirements, the non-K variant provides the same ball screw precision at potentially lower cost. Both share identical mechanical specifications same width, stroke, motor type, ball screw, and guide mechanism.
The LEFS25B-250B-S5 is the standard B-motor S5 configuration at 25mm width and 250mm stroke. For the enhanced K encoder option, specify LEFS25B-250BK-S5. For A-type step motor servo at the same stroke, the LEFS25A-250 provides an alternative motor platform. For shorter stroke, the LEFS25B-200B series reduces overall length. For higher capacity, the LEFS32B at 32mm width increases payload and moment resistance. Always match S-number to your controller platform. Clean series (11-). RoHS compliant.
