The low cost VT-50L linear stage excels in applications with 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-50L is available with an optional linear encoder with 50nm resolution. VT-50L stages can be mounted in XY without any adapters, and Z-axis can be added with the use standard mounting bracket. For elevation travel ranges of 10 mm or less the VT-50L can be combined with the ES-50 elevation stage without the use of adapter plates. Versions capable of operation in vacuum (10-6 mbar) are available. The VT-50L is compatible with the MMC-200 controller.
NOTE: DUE TO NECESSARY BEARING CHANGES, ADVERTIZED TRAVEL IS A FEW MILLIMETERS SHORTER. SEE VT-50L TRAVEL REDUCTION SHEET FOR REFERENCE.
