Mini Size

Built-in Drive (RS-485 or PWM/TTL)

Dynamic Speed Control

Position Control

Current Control

Position/Current Feedback via Data Communication

12V Heavy Duty DC Coreless Motor

Force Control Lineup (12Lf Series) Features
  • The 2nd generation mightyZAP series supporting dynamic speed & current control as well as
    position control along with position & current feedback
  • Built-in drive circuit, position sensor, 12mm diameter coreless DC motor and gear box
  • 27/40/53/90mm stroke option
  • Rated Load of 12N ~ 100N according to gear ratio for each stroke
    * Speed is inversely proportional to Rated Load, so the stronger the Rated Load, the slower the speed.
  • Support RS-485 or TTL / PWM communication
    * TTL / PWM communication version operates by automatically recognizing the input TTL / PWM signal

    * When using PWM communication, only the position command is available without position feedback (For feedback feature, use TTL or RS-485 communication)

  • Both MODBUS RTU and IR open protocols available
