The CMK Series is a motor and driver package consisting of a stepper motor and one of the smallest, lightest 24 VDC input microstepping drivers in the industry, allowing for a reduction in size and vibration in your equipment. There are 5 preset step angles with a maximum microstep resolution of 16 divisions. Operating current is set by a digital switch that is easy to use.
  • Compact driver
  • Standard performance
  • Encoder options
  • Geared option
  • Resolution - 1.8º ~ 0.1125º [5 steps] (Microstep)
  • 24 VDC power supply input
  • RoHS compliant
