Newport MKS Motorized Linear Stage, Miniature, 25 mm Travel, Stepper Motor, M2 and M3 MFA-PPD

The MFA-PPD compact all-steel construction linear stages provide precision 25 mm motion with 0.1 μm Minimum Incremental Motion and excellent stability and stiffness. The MFA-PPD stepper motor offers a more economical solution for less demanding applications. Features include: all-steel construction for high stiffness-to-weight ratio and excellent thermal stability; a double-row linear ball bearing design for ultra-smooth motion; and 4 widely spaced mounting holes for base mounting and XY/XYZ configurations. Typical applications for this stage are fiber optic alignment, laser diode research, bio-medical applications and inspection systems. 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. All Steel Construction A full steel body allows for a more compact design with exceptional stiffness-to-weight ratio, greater thermal stability and high load capacity. 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. Top and Base Plates For more versatility and mounting options, top and base plates may be ordered separately to enable vertical (Z-axis) mounting and mounting to an optical table. For vertical mounting, note that the vertical (Z-axis) stage should be attached to the the MFA-BK first (via the MFA-BK's two counterbored M3 holes), then the combination can be mounted to the horizontal (X- or Y-axis) stage via the MFA-BK's four counterbored M2 holes./p> 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.

Economical Micro-stepping Stepper Motor For less demanding applications, a stepper motor can be a more economical solution than a DC motor. A stepper motor operates using the basic principle of magnetic attraction and repulsion, converting digital pulses into mechanical shaft rotation. To improve the resolution and smoothness of motion, the MFA-PPD features micro-stepping, a method of electronically dividing a full-step of motion into a high number of partial steps.
