The low cost VT-50 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 bearing (optional cross-roller bearing) creates high stiffness and superior performance. The VT-50 is available with an optional linear encoder with 50nm resolution. VT-50 stages can be mounted XY without any adapters, and a Z-axis can be added with the use of a standard mounting bracket. For elevation travel ranges of 10mm or less the VT-50 can be combined with the ES-50 elevation stage without the use of adapter plates. Version capable of operation in vacuum (10-6 mbar) are available. The VT-50 is compatible with the MMC-200 controller.
