The AT20-100 Motorized Vertical Lift Stage from Optimal Engineering Systems, Inc. (OES) is a high-precision and high-load vertical lift stage. It easily integrates into applications. The stage has a 120 x 180 mm drilled and tapped platform with vertical travel of 100 mm and moves with 3.315 µm (non-microstep) resolution, 5 µm repeatability, and 15 µm positional accuracy.

The precision ground lead screw, precision linear bearings, and the rigid box construction of the moving component of the elevator stage assures smooth, flat (parallel to mounting surface) vertical motion.

Applications  for theAT20-100 vertical lift stage include testing, inspection, assembly, sampling, laser drilling and machining in a broad range of industrial, medical, semiconductor, and research facilities.

The AT20-100 Vertical Lift Stage (lowered position) is 318 mm high. The stage is constructed of black-anodized aluminum alloy and steel shafting, and weighs just 10.5 kg.  The powerful 2-phase NEMA Stepper and precision ground lead screw offers a high load capacity to 50 kg without the concern for cantilevered effects (loss of parallelism), additionally, the moving platform has access from all four sides.

The limit switches prevent over travel, a hand knob on the extended motor shaft is for manual adjustments, and the base plate has easy to access holes for mounting. AT20-100 Vertical Lift Stage options include optical encoder, servo motor, and linear encoder.  It is also available as a complete plug-and-play system with a motion controller.
