The SMC 11-LEFS25B-250BK-S5 is a clean room specification electric actuator from the LEFS series with B-type motor and S5 configuration. Part number decoded: LEFS = LEFS series ball screw electric actuator, 25 = 25mm width, B = B-type servo motor, 250 = 250mm stroke, B = additional specification, K = specific option (typically related to motor encoder or controller interface), S5 = configuration option specifying the controller communication interface.
The K option in the LEFS part number typically designates a specific encoder resolution, motor feedback type, or controller communication protocol. The S5 configuration specifies the controller interface standard, which determines how the actuator communicates position commands, speed parameters, and status signals with the motion controller. Different S-number configurations correspond to different SMC controller models and communication standards, ensuring correct signal compatibility.
The LEFS25B-250BK-S5 provides B-type motor operation with S5 controller interface at 25mm width and 250mm stroke. For the same stroke without K option, the LEFS25B-250B-S5 provides the base B-motor S5 configuration. For A-type motor at 250mm, the LEFS25A series provides step motor servo alternatives. For longer stroke with the same configuration, specify larger stroke values with BK-S5 suffix. Always verify S-number compatibility with your installed controller. Requires compatible motor controller. Clean series (11-). RoHS compliant.
