Zaber Technologies Logo
  • 20 mm travel
  • Up to 55 mm/s speed and up to 200 N thrust
  • 10 kg load capacity
  • 73 mm retracted height
  • Built-in, 500 CPR, motor encoder provides slip/stall detection and recovery
  • Designed for use with an X-MCC Series stepper motor controller or any 2-phase stepper motor controller
  • With Auto Detect, the X-MCC controller configures its settings automatically for the connected peripheral



1. Panel mount DB15 with Auto Detect allows the stage to be easily connected to an X-MCC series controller and ready to use without additional user input.
2. Top mounting surface for M6 and M3 fasteners.
3. Easy access slots for M6 and 1/4-20 fasteners.
4. Speed up to 55 mm/s.
5. 73 mm tall when closed.

Zaber Technologies’ VSR-E vertical lift stages are stepper actuator driven platforms capable of moving 10 kg loads. They deliver exceptional travel and load capacity for their compact sizes, measuring only 73 mm tall when closed. With small footprints these stages can also mount directly onto Zaber Technologies’ LRT-C and LSQ series of linear stages.

The stages are designed to connect directly to our X-MCC Series universal motor controllers, or they can be used with any 2-phase stepper motor controller through the panel mount DB15 connector. Set up is easy with Auto Detect. Once connected, the X-MCC controller will automatically detect and configure the VSR-E.
