Blackmagic Design Cable Lanc 350mm

Blackmagic Design LANC Cable (350mm)

The Blackmagic Design LANC Cable (350mm) is a specialized, short-length control cable used to connect the camera’s handgrip to the camera body. LANC (Logic Application Control Bus System) is the industry-standard protocol that allows you to trigger camera functions remotely.

In 2026, this cable is most commonly used by operators who have mounted their URSA Mini or URSA Broadcast on a shoulder rig and need a reliable, low-latency connection for the side handle.

Core Functionality

• Command Transmission: This cable carries the signals for Record Start/Stop, Iris Adjustment, and Focus Control from the buttons on the handgrip directly to the camera’s internal processor.

• Low Profile Design: At 350mm (approx. 13.7 inches), this cable is designed specifically to span the distance between the camera body and the handgrip when used with the URSA Mini Shoulder Kit Extender Arm.

• Right-Angle Connectors: It typically features a right-angle 2.5mm jack on at least one end. This prevents the cable from sticking out too far from the side of the camera, reducing the risk of it being snapped off or snagged on clothing while the camera is on your shoulder.

Key Features

• Strain Relief: Built with reinforced molding at the connector heads to withstand the constant pivoting and movement of a telescopic extender arm.

• Shielded Wiring: Prevents electromagnetic interference (EMI) from nearby wireless video transmitters or power cables, ensuring that a "Record" command is never missed.

• Universal 2.5mm Jack: While branded by Blackmagic, it uses the standard 2.5mm LANC jack, making it technically compatible with other LANC-enabled accessories if the length is appropriate.

Technical Specifications

When Do You Need This?

• Shoulder Rig Setup: If you are using the URSA Mini Shoulder Kit, the original cable that comes with the handgrip is often too short or becomes worn out over time. The 350mm length is the "Goldilocks" size for a fully extended arm.

• Gimbal Operation: When mounting an URSA to a large gimbal (like a DJI Ronin 2), this cable can be used to relocate the handgrip to the gimbal's ring or frame for easier thumb-control of the iris and recording.

Operational Insight (2026)

In 2026, the LANC protocol remains a favorite because it is hard-wired. Unlike Bluetooth control, which can suffer from lag or interference in crowded wireless environments (like trade shows or stadiums), a LANC cable provides an instantaneous response.

Pro Tip: Always ensure the cable has a small amount of "slack" or a loop near the handle. If the extender arm is pulled out to its maximum length and the cable is taut, you risk damaging the 2.5mm port on the camera body, which is a costly repair.
