The SMC 11-LEFS25B-50BK-S1 is a clean room specification electric actuator from the LEFS series with B-type motor and an extremely short 50mm stroke. Part number decoded: LEFS = LEFS series ball screw electric actuator, 25 = 25mm width, B = B-type servo motor, 50 = 50mm stroke, B = additional specification, K = encoder/feedback option, S1 = controller interface configuration.
A 50mm stroke on a 25mm width ball screw actuator creates a precision micro-positioning platform with the payload capacity of the 25mm body but travel equivalent to a small pneumatic cylinder. This configuration is used when the application requires electric precision (multi-point positioning, variable speed, programmable acceleration) over a very short distance that pneumatic cylinders cannot achieve with the same control. Typical applications include fine Z-axis adjustment in clean room bonding equipment, precision gap control in coating or dispensing processes, and micro-height positioning of optical inspection systems.
The LEFS25B-50BK-S1 is the shortest-stroke LEFS25 variant. For longer strokes at the same width, options range from 150mm to 600mm. For the same 50mm travel without electric precision, the CQS or CQSX compact guided pneumatic cylinders provide two-position actuation at lower cost. For the K encoder option at longer strokes, the LEFS25B-250BK-S5 provides enhanced feedback over 250mm. The S1 controller interface must match your installed controller. Clean series (11-). RoHS compliant.
