Elevator Stage

Optimal Engineering Systems, Inc. (OES) has unveiled its DAG40-200 series that includes four motorized elevator stages. Featuring a 200mm x 200mm table, the stages feature 40mm of vertical travel with a 30kg load capacity. The DAG40-200-01 and the DAG40-200-04 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 5mm per second travel speed. The DAG20-120-04 (pictured) features a quadrature incremental optical encoder for position verification. The DAG40-200-02 stage is driven by a three-phase brushless servo motor while the DAG40-200-03 stage by a DC brushed servo motor. Both stages have a quadrature incremental encoder.
