Optimal Engineering Systems Motorized vertical lift stages

These AT20-30 high-precision vertical lift stages can elevate heavy loads by 30 mm (1.18 in) in an ultra-low-profile design. The elevator stage’s moving component has a rigid box construction and travels on six slide rails, assuring smooth vertical travel and parallelism of the table and mounting surface at all times. The vertical lift stage features 3.315-micron (full-step) resolution, 5-micron repeatability and 15-micron positional accuracy. Motor options include two-phase stepper motor, single-phase dc servo motor for closed-loop operation and a three-phase brushless servo motor for higher precision and travel speeds. The stages can be ordered as complete plug-and-play motion control systems.
