New: Linear Actuator for the Ultra-High-Vacuum and Cryogenic Environment! 

Research, development and manufacturing processes are increasingly taking place in a vacuum and sometimes in extremely cold conditions. For this, drive components are required that will function precisely and reliably in these extreme conditions, such as the new linear actuator from Phytron GmbH.

The new linear actuator (LA) marks the dawn of a new era for low temperatures down to -269°C. Previously, drive units were shielded from these extreme environments by placing them outside the chamber and using mechanical feedthroughs. Through intensive research and with new approaches to analysis and measurement the actuators can now reliably operates within an ultra-high vacuum (UHV) or in a cryogenic environment.

Inside, the LA lies the knowledge gained from over 30 years of developing in-vacuum and cryogenic stepper motors. "Our newly developed linear actuator delivers reliability, power and precision in extreme environmental conditions and greatly simplifies customer mechanisms because there is no need to operate in cryo-vacuum chambers", explains Henning Brunke, Technical Manager at Phytron, summarizing the development.
Partly made from Titanium, the dry-lubricated actuator can also be operated near sensitive optics without contaminating them by outgassing.

The first version of the 25mm size provides a linear stroke of 13mm. With a positioning precision to <0.01 mm, a load of 10N can be moved. In combination with an integrated planetary gear, this can actually be increased to 30N.
During the course of the year, the linear actuator will be scaled up to sizes 32mm and 42mm, thus specifically expanding Phytron's portfolio of automation solutions for extreme environmental conditions.
