LSA-V2 Series: High vacuum micro motorized linear stages
Vacuum compatible to 10-6 Torr
10 or 25 mm travel
Up to 10 mm/s speed and up to 35 N thrust
< 25 nm microstep size
Fits into the most restrictive spaces
Mounts directly in XY (requires AB106 angle bracket for Z axis/vertical mounting)
Only 7 feedthrough wires required to control these units
Designed for use with a X-MCB1 Series stepper motor controller or any 2-phase stepper motor controller
For more information about the basics of a vacuum system and considerations to keep in mind when gathering requirements for your application, read our technical article, "Motion Device Design Considerations for Vacuum Applications".
Zaber's LSA-V2 series stages are designed to fit into the smallest spaces, without sacrificing performance or features. Small but powerful, these stages have up to 10 mm/s speed and up to 35 N thrust. With a microstep size of less than 25 nm, they allow for reliable ultra-fine positioning in vacuum environments.
The LSA-V2 stages can be wired for plug-and-play use with our X-MCB1 Series stepper motor controllers. Only 7 feedthrough wires are required to control this device in a vacuum chamber.

Specification Charts and Notes
Thrust or torque is a function of speed. The values given above are maximums. These values cannot both be achieved simultaneously (i.e. at maximum speed, the unit will not produce maximum thrust).
