Motorized Linear Stage, Miniature, 25 mm Travel, DC Motor, Vacuum Compatible

The MFA-CCV6 Vacuum Compatible Miniature Linear Stage is designed for space-limited applications and compact multi-axis assemblies. It is a high resolution, single-axis 25 mm stage in a low-cost, motorized package. Typical applications for this stage are fiber optic alignment, laser diode research, bio-medical applications and inspection systems. The MFA-CC is the choice for applications that require small incremental motion, high dynamic speed range and good repeatability.
Note: The connector supplied with the stage is not vacuum compatible due to various feed-through configurations and customer preferences. Please contact Newport for vacuum compatible connector options.

Double Row Linear Ball Bearing Slides

Newport's proprietary double-row linear ball bearing design with bearing ways that are directly machined into the structural frame of the stage result in very smooth travel, greater durability and longer life. Compared to other solutions that use commercial bearings, MFA linear stages have a higher load capacity and stiffness with low pitch and yaw errors.

High Speed DC Motor with High Resolution Feedback

DC motors are best characterized by their high speeds, smooth motion, good efficiency and a high power/weight ratio. The MFA-CC DC motor features an integrated gear-box and a motor-mounted rotary encoder. The high-resolution 2,048 cts/rev rotary encoder provides position feedback. Combined with a low-friction mechanical design, the MFA-CC delivers ultra-smooth motion with 100-nm sensitivity. Faster motion with higher reliability and lower backlash make DC Motor-driven stages ideal for applications requiring small incremental motion with high dynamic speed and good repeatability.

Vacuum Compatible Version

The is the vacuum compatible version of the MFA DC motor stage. It can be used in a vacuum environment down to 10^-6 hPa.

End-of Run Limit Switches

The stage contains end-of-run limit switches on both ends to prevent damage to the stage from over-travel.
