Motorized Linear Drive for MD16 Feedthrough

Product code: DRVMDMOTL16-XXXX

The DRVMDMOTL16 is a stepper motor-driven one axis linear actuator. It's high precision motorized spindle drive is coupled to the outer magnet and controls linear motion. With a 2mm pitched spindle, a resolution of 0.01mm is possible. Alternatively, a 1mm pitched spindle provides even higher resolution. The linear axis is driven by a Nanotec ST2018L0804 2-phase stepper motor.
The sturdy linear unit ensures unchanging alignment of all components and consistent positioning.

MD16 linear drives can be equipped with the DRVMDMOTL16 option and configured with either continous rotation of the shaft or as a linear only drive.

Please note that for bakeout the drive must be removed.
