OES’ 30MM VERTICAL LIFT STAGE
Optimal Engineering Systems Inc. (OES) has released the AT20-30 series of motorized vertical lift stages featuring sub-micron resolution, very high parallelism, and a vertical lift of 30mm. The AT20-30-01 (pictured) is driven by a two-phase stepper motor that features a repeatability of 5 microns, positional accuracy of 15 microns and a Full Step resolution of 0.2 microns. This stepper motor driven stage also has a knob on the motor for manual adjustment. The AT20-30-02 is driven by a brushless DC servo motor with a quadrature incremental encoder and the AT20-30-03 is driven by a brushed DC servo motor with a quadrature incremental encoder. Each of the servo motor options, the -02 and -03 versions, offer faster travel speeds. The AT20-30-04 is driven by a two-phase stepper motor that has a quadrature incremental encoder for position verification. The 500mm by 300mm stage table has a pattern of threaded mounting holes, and the rigid box construction of the moving component of the elevator stage travels on six slide rails always assuring smooth vertical travel and high parallelism of the table to the mounting surface. The hih 100kg load capacity of the AT20-30 series stages allows for positioning of: multi- axis stages, flasks, stirrers, hotplates, and other lab equipment, testing, inspection, assembly, sampling, laser drilling and machining, in a broad range of industrial, medical, semiconductor, and research applications. The AT20-30 motorized vertical lift stage (lowered position) is 269mm high and weighs 35kg. Constructed of black-anodized aluminum alloy and steel shafting, it incorporates a center mounted, precision ground lead screw having a transmission ratio of 40 microns per motor revolution. Additionally, the stage has access from all four sides. Limit switches prevent over travelling and the large base plate has easy access to mounting holes. The AT20-30 vertical lift stage series is also available as a complete plug-and-play system with a motion controller, drivers, keypad, and joystick.
