PI’s palm-sized motorized positioning stage combines precision with long lifetime components, making it more attractive to research and industry. PI (Physik Instrumente) has released a low-profile motorized positioning stage – the M-122 – with a very small footprint of 60x86mm and a travel range of 25mm, best suiting it for research and industrial applications including fiber alignment, metrology, quality assurance testing, photonics packaging, test equipment, and micromachining.
Closed-loop position control — Optical linear encoder with 1,000-nm resolution
The compact closed-loop positioning stage can handle payloads to 11 lbs, with velocity to 20mm/sec. The optical linear encoder provides 100 nanometers resolution and better linearity and repeatability compared to rotary encoder or stepper motor equipped positioners. Long service life and excellent guiding accuracy with minimal backlash are guaranteed by the preloaded ball-screw drive and precision crossed roller bearings with anti-creep cage assist.
XY and XYZ combinations, affordable packages: M-122 stages can be combined to create very compact XY and XYZ systems. Combined with the networkable low-cost C-863 Mercury servo motor controller, M-122 stages offer high performance at a competitive price. Get specifications, a datasheet, and more information here.
