Motorized Miniature Translation Stage is Affordable and Precise, Newly Released by PI
PI (Physik Instrumente) LP Posted 12/20/2018
A new family of compact motorized translation stages is available from PI.
Auburn, MA –The L-408 linear stage strikes a good balance of load capacity, precision, and low cost. It has applications in research and industry including optics, bio-tech, and assembly of miniature components and photonics instrumentation.
Compact and Precise
PI’s new compact X-axis linear stage provides precise motion and reliability with anti-creep crossed roller bearings. Driven by a high resolution leadscrew with 0.5mm pitch, minimum incremental motion of 0.1 microns (100nm) is achieved over a travel range of 1 inch (25mm).
Up to 44lbs Payload (200N) and 11lb Push/Pull Force (50N)
Despite its compact dimensions, the stage can handle payloads of 44lbs (200N) and provides a push/pull force of 11lbs (50N).
What Drives It?
Stepper and servo motors are offered with direct-drive and gearbox options. The maximum velocity of the direct-drive stages is 10mm/sec. The unidirectional repeatability of all versions is 0.5 microns. High resolution, motor-mounted optical encoders provide position feedback to the motion controller for closed-loop operation.
Noncontact, optical limit switches and reference point switches with direction sensing in the middle of the travel range simplify use in automation tasks.
