The AT20-100 Motorized Vertical Lift Stage is a very stable,
high precision, high load vertical lift stage that can be easily integrated into
The large 120 mm x 180 mm (4.72 in. x 7.08 in.) drilled
and tapped platform has a vertical travel of 100 mm (3.93 in.) and features:
3.315 µ (non- Micro-Step) resolution, 5 µ repeatability, and 15 µ 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 the AT20-100 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
(12.52 in.) high. The stage is constructed of black-anodized aluminum alloy and
steel shafting, and weighs just 10.5 kg (23.15 lbs). The powerful 2-phase NEMA
23 stepper motor and precision ground lead screw offers a high load capacity to
50 kg (110 lbs.) 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
The AT20-100 Vertical Lift Stage options include: Optical
encoder, servo motor. It is also available as a complete plug-and-play system
