LEFS25B-350B-R8CP17 Applications
The SMC LEFS25B350BR8CP17 is used in electronics assembly, packaging, laboratory automation and general pick-and-place machinery that needs accurate, programmable linear transfer. It is suited for horizontal and vertical transfer where the motor lock holds position on power-off, for PROFINET-networked cells controlled from a JXC series controller, and for moving jigs, cameras or grippers over a 350 mm span. The 6 mm lead trades speed for thrust and resolution, making it a good fit for heavier vertical loads, while the 8 m robotic cable suits moving cable-track installations.
