Product Family Description

  • Two Knob Options for Stages
  • 3 Travel Options for Tracks: 125mm, 250mm, and 550mm
  • Common Stage and Track Combination Pre-Assembled

These linear positioners are ideal for long travel breadboard applications. Simply select a stage and then a track with the travel that is right for your application. Track is made from extruded aluminum into a low-profile dovetail design to fit snugly against the mating dovetail of the mounting stage. Helical movement on brass rack allows for precision, smooth travel along the entire length of track. Each track includes a scale that is aligned with the stage vernier. The stage is available in either one knob or two knob (not shown) configurations with a coarse movement that can be aligned within 0.1mm. Combination of stage and track has total height of 40mm; knobs do not exceed stage height. Multiple stages can easily be added onto a track; there are no screws to remove. Tension screws in stage allow for convenient control of fit between stage and track without the difficulty of a loose, separate gib found on other designs.
