ARRI K2.0008819 overview

  • 1Description

ARRI's cforce Plus Motor is a strong, LBUS-connected motor used to remotely control your lens's focus, iris, or zoom function. With more torque than its cforce Mini cousin, the cforce Plus has the power to control any standard lens quickly and smoothly. Directly compatible with ARRI ALEXA Mini cameras and cmotion units, the cforce Plus Motor can be paired with an AMC-1 or UMC-4 controller when working with other ARRI or third-party cameras. Up to three cforce Plus Motors may be daisy-chained together, saving the space and weight of individual controllers in your camera rig.

The cforce Plus Motor offers compatibility with the same mounting options as the ARRI CLM-4 motor, including a Hill Bracket and standard rod mounts. The cforce Plus weighs about 11 ounces with a gear and bracket (available separately). This basic motor unit requires a separately available gear, cable, and bracket.

Note: In certain situations (low battery power or stiff lenses) cforce motors require an additional power supply connected directly to the motors when controlled by the UMC-4 or ALEXA Mini
