Compact linear stage offers precision for high duty cycle applications

18 February 2016

Physik Instrumente (PI) has introduced a linear stage series with optional dc or stepper motor that offers compactness and a load capacity up to 100N.

The L-509 linear stages are available for travel ranges of 26mm, 52mm and 102mm. The linear axes, with crossed roller guides and ball screws, are suitable for applications in industry and research and offer a high lifetime at velocities up to 20mm/s. A stress-relieved aluminium base ensures high stability.

A high-resolution, integrated rotary encoder takes care of the position metrology in the versions with dc gear motor. As an option, stages with stepper motor are available with a high-resolution linear encoder. When controlled by an SMC Hydra controller, they achieve a repeatable minimum incremental motion of 0.01µm.

The non-contact, optical limit switches and reference point switches with direction sensing in the middle of the travel range also simplify use in automation tasks.

For single-axis control, PI offers the easy-to-operate digital C-863 and C-663 Mercury motion controllers for dc motors and stepper motors; dc servo motor control of up to four axes is possible with the C-884.
