OES 60mm stages’ combines scissor lift design with precision roller bearings and and slide rails.
Optimal Engineering Systems, Inc. (OES) released its AT10-60-01, AT10-60-02 and the AT10-60-03 motorized elevator stages. The stages feature tables measuring 120mm x 80mm (4.724 in. x 3.149 in.) with a vertical travel of 60mm +/-2mm (2.362 in. +/-0.078 in.) and a load capacity of 5.0kg (11.0 lbs). The AT10-60-01 (shown) is driven by a two-phase stepper motor with micro-stepping capabilities. The repeatability is typically +/- 5 micron and typical positional accuracy is 15 micron. The knob for manual adjustment can be replaced with a quadrature incremental optical encoder for position verification.
The AT10-60-02 is driven by a three-phase brushless servo motor with a quadrature incremental optical encoder for the higher repeatability, positional accuracy, and travel speeds typical of a closed loop system. The AT10-60-03 is driven by a DC servo motor with a quadrature incremental optical encoder. All stages require a motion controller and can be ordered with RS-232, USB, joystick, trackball, and keypad control.
