Description


The low cost VT-21S linear stage excels in applications with very limited space due to its compact design. The stage utilizes a 2-phase stepper motor and is equipped with two mechanical limit switches. A pre-loaded ball slide creates high stiffness and superior performance. The VT-21S is available with an optional linear encoder with 50nm resolution. The stages can be mounted in XY or XYZ configuration in a space-saving arrangement. Versions capable of operation in vacuum (10-6 mbar) are available. The VT-21S is compatible with the MMC-200 controller.
