The use of rotary or linear mechanisms in cryogenic environments is always a matter of concern because of the intrinsic cryogenic design complexity and testing constraints.
LIDAX has completed the development of a linear actuator with extensive cryogenic testing and strict configuration control to ensure product performance repeatability in future manufactured units, and to provide a reference frame for current and future cryogenic fine positioning developments.
The Cryogenic Submicron Linear Actuator (CSA) is a medium range (±5 mm) submicron resolution linear actuator suitable to be used at cryogenic temperatures.
Main features are as follows:
- Type Push-Pull
- Range ±5 mm
- Load >20N
- Speed 0-0.1 mm/s
- Operating Temp 12-300K
- Resolution <50 nm
- Mass 290 gr
- Size Ø26mmx150mm
The unit has been developed for fine positioning use and is based on stepper motor, planetary gear and nut & screw concept; this standard configuration allows easy upgrade for load, speed or resolution for more demanding applications.
