SMC 11-LEFG16-S-50 | Clean Room Electric Actuator LEFG Series Slider Type 16mm Width 50mm Stroke Support Guide

The SMC 11-LEFG16-S-50 is a clean room specification electric actuator from the LEFG series, configured as a slider type with support guide. Part number decoded: LEFG = LEFG series electric actuator with slider and guide, 16 = 16mm width (body cross-section), S = support guide type, 50 = 50mm stroke. The LEFG represents SMC's transition from pneumatic to electric motion control for clean room applications requiring precise positioning, variable speed, and programmable motion profiles.

Unlike pneumatic cylinders that provide two-position (extend/retract) control, the LEFG electric actuator enables multi-point positioning, variable speed control, and programmable acceleration/deceleration profiles. The support guide mechanism provides rigid linear guidance similar to the CXS dual rod concept but driven by an electric motor instead of air pressure. This enables precise positioning at any point along the 50mm stroke with repeatability specifications far exceeding pneumatic alternatives. Applications include precision dispensing, variable-height inspection, programmable assembly operations, and any clean room task requiring flexible positioning.

The LEFG16-S-50 is the smallest LEFG variant, suited for light-duty precision positioning. For larger slider widths with higher load capacity, the LEFG32 and LEFG40 provide 32mm and 40mm width options. For ball screw driven electric actuators with higher force and precision, the LEFS series provides an alternative drive mechanism. For simple two-position actuation where electric precision is unnecessary, pneumatic CXS or CQS cylinders provide lower cost. Requires an SMC-compatible motor controller. Clean series (11-). RoHS compliant.
