For Applications in Ultra-High-Vacuum and Cryogenic Environment Motors for use in vacuum should not only withstand the vacuum (no bursting of air inclusions), they must not contaminate the vacuum either. Through many years of experience with special materials for use in Space, we have put a focus on materials with minimal molecular outgassing and high heat resistance. This is the prerequisite for a high vacuum quality and genuine measurement results in scientific and medical applications. For exact positioning in vacuum, stepper motors are therefore particularly suitable because they can precisely position even without sensitive feedback providers. Therefore phytron linear actuators can be used in particularly challenging environmental con- RoHS complient in focus ditions (radiation, cryo-temperatures). Since stepper motors do not generate jitter effects while holding a position, this technology is ideal for precisely aligning optical instruments, mirrors, antennas or samples e.g. in high-resolution microscopes, particle accelerators or molecular analysis devices. phytron LA linear actuators for cryo (UHVC1;UHVC2) and UHV (UHVS) are completely dry lubricated. Highlight Cleanliness phytron motors for use in ultra high vacuum (UHV) contain only materials that also meet the requirements of the ECSS (European Space regulations). Thus, each material has a maximum TML (Total Mass Loss) value < 1% and a maximum CVCM (Volatile Mass Losses) value < 0.1 %.
