Motorized Linear and Rotary Manipulator DN40CF


The MD40-DRVMDMOTLR is a linear/rotary feedthrough, equipped with a motorized two axis actuator. It's Nanotec ST2018L0804 2-phase stepper motor-driven high precision spindle drive is coupled to the outer magnet and controls linear motion. With a 2mm pitched spindle, a readout of 0.05mm is possible. Alternatively, a 1mm pitched spindle provides even higher resolution.

Rotation of the shaft is activated via the gearbox of a second stepper motor.
The sturdy linear unit ensures unchanging alignment of all components and consistent positioning.
