Four new motorized elevator stages, the DAG40-200 series, have been released by Optimal Engineering Systems, Inc. (OES). High-precision ball-bearing profile rails assure high parallelism and smooth motion throughout the raising and lowering of the 200 x 200 mm table. These high resolution, compact, low-profile elevator stages feature 40 mm of vertical travel with a high 30 kg load capacity. These vertical travel or Z-axis stages are suitable for microscopy, inspection, metrology, positioning, photonics, sampling, and laser drilling and machining.
The DAG40-200-01 and the DAG40-200-04 motorized elevator stages are driven by two-phase stepper motors featuring 2 micron positional accuracy, and a resolution of 0.042 microns (with a 10 micro-steps per step motor driver in use), and 5 mm/sec travel speed. The knob for manual adjustment on the DAG20-120-01 is replaced with a quadrature incremental optical encoder for position verification on the DAG20-120-04 (pictured).
The DAG40-200-02 stage is driven by a three-phase brushless servo motor and the DAG40-200-03 stage by a dc brushed servo motor. Each of these stages has a quadrature incremental encoder for closed-loop servo operation offering higher resolution, accuracy, and travel speed.
These compact, black anodized aluminum alloy stages measure 200 x 200 x 165 mm high at the raised position, with limit switches preventing over traveling. The table of each stage has a precise pattern of threaded holes for fixtures or tooling, and holes in the base allow for easy integration into a new or existing application.
These stages require a motion controller that can be ordered as a complete plug-and-play system with RS-232, USB, joystick, trackball, and keypad from OES.
