Main Features

FORCE Control

  • Stall Force and current control based on current feedback
  • Current feedback allows detection of objects and obstacles
  • Possible to maintain constant force for a certain time (Applicable to Gripper, etc.)
  • Precision position & Dynamic speed control
  • 30~50μm Unidirectional repeatability & Position feedback (Varied by each stroke version. See spec chart.)
  • Absolute position sensing via Potentiometer (No Calibration needed)
  • 32Bit Micro controller, High resolution (4096) A/D converter
  • 1024 steps dynamic speed control (Fastest speed is default.)


Durability & Safety

  • Heavy Duty Reliable 12V coreless DC motor with 7 ~ 13V input voltage range
  • Metal alloy rod
  • Engineering plastic case (27mm stroke version)
  • Aluminum stroke case & engineering plastic motor case (40mm / 53mm / 90mm)
  • Current control allowing longer life cycle & safer control
  • Life-cycle Reference Data is on our website (Under 50% duty cycle recommended)
  • Vertical (Z axis) use is possible due to mechanical Self-lock (Certain models are not applicable, see the model chart)
  • Smart overload protection by calculation of cumulative current
