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
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.
