Optimal Engineering Systems, Inc. (OES) has released two new motorized elevator stages, the DAG20-120-01 and the DAG20-120-04. These high-resolution, compact, low-profile elevator stages feature high stability 120 x 120 mm tables and 20 mm of vertical travel. High precision ball bearing profile rails assure high parallelism and smooth motion throughout the raising and lowering of the table. These Z-axis stages are suitable for applications in microscopy, inspection, metrology, positioning, photonics, sampling, and laser drilling and machining.
Driven by two-phase stepper motors, the DAG20-120-01 and the DAG20-120-04 motorized elevator stages feature 2 micron positioning accuracy, and resolutions of 0.03 microns (with a 10 micro-steps per step motor driver in use). 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. The load capacity of these compact stages is 20 kg.
These compact, black anodized aluminum alloy stages measure 181.8 x 120 x 115 mm high at the raised position. Speed of travel is 5 mm/sec and limit switches prevent over travelling. 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 control.
