Nucleus-M Run/Stop Cables Arri - Camera R/S Cable for Nucleus-M

Our review of the Nucleus-M Run/Stop Cables Arri focuses on a simple but important function: enabling remote run/stop from the Nucleus-M system to Arri-compatible cameras. This cable is aimed at operators who already use the Tilta Nucleus-M motor rig and need a clean, reliable connection from a motor to a camera R/S port. The bottom line: it does one job and does it without fuss, offering a compact 27in length, lightweight build, and robust connectors designed for on-set use with the Nucleus-M hand unit and grips.

Key Features

• Dedicated compatibility: The cable is built specifically for the Nucleus-M so the run/stop function works seamlessly with the Nucleus-M hand unit and hand grips.
• Durable materials: Copper conductors with rubber insulation and aluminum-alloy housings provide a balance of flexibility and durability suitable for repeated on-set use.
• Professional connectors: The 7-pin LEMO type and 3-pin Fischer type connectors ensure secure, low-profile connections between motor and camera R/S ports.
• Compact length: At 27in (68.6cm) the cable is long enough for typical rigging while staying tidy in gimbals and compact rigs.
• Lightweight: Weighing 1.44 oz (40.8g), the cable adds minimal load to motors and accessories, keeping balance and responsiveness intact.

Who It's For

This cable is for cinematographers, gimbal operators, and rental houses that already use the Tilta Nucleus-M ecosystem and need to add reliable run/stop control to Arri-compatible cameras. It suits setups where short, well-terminated cables are preferred to avoid excess slack around motors or tight camera cages.

Those who should look elsewhere are users who do not own the Nucleus-M system, or operators needing multi-camera or longer-distance R/S routing; the cable is purpose-built and the R/S function is limited to the Nucleus-M hand unit and grips.

Pros & Cons

Pros

• Purpose-made compatibility with Nucleus-M ensures plug-and-play run/stop control.
• Solid construction with metal connector housings that stand up to rigging and handling.
• Short, lightweight form factor reduces weight on motors and keeps rigs tidy.

Cons

• R/S only works with the Nucleus-M hand unit and grips, so it is not a universal camera remote cable.

Our Verdict

Frequently Asked Questions

Will this cable work with cameras other than Arri?
The cable uses a 3-pin Fischer type R/S connector commonly found on Arri cameras; it may fit other cameras with the same connector but the run/stop function is designed for the Nucleus-M system.

Can I use the R/S function with any hand unit?
No. The run/stop feature only operates when used with the Nucleus-M hand unit and Nucleus-M hand grips.

Is the cable durable for heavy use?
Yes. The cable uses copper conductors, rubber insulation, and aluminum-alloy housings for the connectors, which together offer a rugged build for regular on-set handling.
