PI News: M-122 Miniature Precision Linear Translation Stage with Linear Encoder is Faster; M122

M-122 Miniature Linear Translation Stage Features Optical Linear Encoder and Direct Drive

The M-122 palm-top-sized precision translation stage combines small dimensions, high speeds and very high accuracy at a competitive price. It features a space-saving, folded drive train with the servo motor and drive screw side-by-side. Equipped with a non-contacting optical linear encoder and a preloaded, precision-ground, ball-screw, these stages can provide much higher accuracy and better repeatability than conventional stepper motor stages or rotary encoder-equipped servo motor stages.

>> Miniature Translation Stage Selection Guide

  • Precise: 0.1 µm Resolution Optical Linear Encoder for Highest Accuracy & Repeatability
  • High Load & Excellent Guiding Accuracy: Cross-Roll Bearings
  • Travel Range 25 mm
  • Fast: Max. Velocity 20 mm/s
  • Long Life & Low Maintenance: Recirculating Ball Screw Drives Provide High Speeds & Long Lifetimes

Very Compact XY and XYZ Combinations
M-122 stages can be combined to very compact XY and XYZ systems. The M-122.AP1 mounting bracket is available to mount the Z-axis.

Low Friction, High Speed, Maintenance-Free
Due to its low-friction, the backlash-free ball screw yields significantly higher mechanical efficiency than leadscrews, and allows maintenance-free, high duty-cycle operation at high velocities up to 20 mm/sec.
