DJI Matrice 400 Third Gimbal Connector

The DJI Matrice 400 Third Gimbal Connector is a heavy-payload mount that attaches to the underside of the Matrice 400 and connects to the aircraft's E-Port V2 (positions E3 and E4). It adds a third gimbal position for a single stabilized DJI Zenmuse payload or a custom DJI Payload SDK device, and it is the connector rated for the aircraft's full payload capacity: up to 6 kg with screw-lock fastening or 3 kg with the quick-release port. In fact, DJI measures the Matrice 400's 6 kg max payload at this connector. Use it to fly a heavier sensor than the front connectors allow, or to run a third payload alongside a dual-gimbal setup mounted at the front.

Underside heavy-payload mount for the DJI Matrice 400. Adds a third gimbal position on the E-Port V2 with up to 6 kg screw-lock or 3 kg quick-release capacity.

Features

• Adds a third gimbal position on the underside of the Matrice 400 for a single DJI Zenmuse payload or a DJI Payload SDK device
• Rated for the aircraft's full payload capacity: up to 6 kg with screw-lock fastening or 3 kg with the quick-release port (6 kg measured at sea level; capacity decreases with altitude)
• Connects to the Matrice 400's E-Port V2 at positions E3 and E4, delivering full data, control, and power through DJI's standard payload bus
• Two fastening options with different weight ratings: up to 6 kg with screw-lock fastening or 3 kg with the quick-release port
• Supports DJI Zenmuse gimbal cameras and custom payloads built on the DJI Payload SDK, useful for integrators running domain-specific sensors
• Can be combined with a front-mounted single or dual gimbal connector for multi-payload configurations within the aircraft's total payload envelope
• Heavy-duty construction that complements the Matrice 400 airframe

Specifications

Gimbal connector options for the Matrice 400

The Matrice 400 supports several gimbal connectors, each with a different payload rating. The Third Gimbal Connector is the one to reach for when you need maximum single-payload weight or a payload position on the underside.

Who this is for

• Matrice 400 operators who need to fly a heavier payload than the top-side single or dual connectors allow
• Surveying, mapping, and inspection crews running large LiDAR, photogrammetry, or specialized sensors that exceed the standard connector weight limits
• Integrators developing or deploying custom DJI Payload SDK devices that need the underside position and the higher weight rating
• Teams building multi-payload configurations who want a third gimbal position underneath in addition to a front-mounted payload

What's included

• 1 × DJI Matrice 400 Third Gimbal Connector

Installation and operational notes

• The Third Gimbal Connector mounts to the underside of the Matrice 400 and connects to the E-Port V2 at positions E3 and E4. Follow the procedure in the DJI Matrice 400 user manual to attach the connector and payload in the correct order.
• Choose the attachment method for the job: screw-lock for the full 6 kg rating and a more secure hold, or quick-release (3 kg) when you need to swap payloads quickly in the field.
• The 6 kg figure is measured at sea level. Payload capacity decreases as altitude increases. Refer to the user manual for the derating curve at your operating elevation.
• Verify the payload is recognized in DJI Pilot 2 before takeoff and confirm the aircraft's center of gravity is within the manual's tolerance after installation.
• Heavier payloads change the aircraft's flight envelope. Expect reduced flight time and tighter wind-resistance margins versus a lighter configuration.
• Power down the aircraft before installing or removing the connector or payload. DJI's payload interface is not rated for hot-swapping.

Please note: The Third Gimbal Connector is built for the DJI Matrice 400 only. It is not compatible with the Matrice 350 RTK, Matrice 300 RTK, Matrice 30 Series, Matrice 4 Series, or any other DJI aircraft, which use different payload interfaces. Verify your aircraft model before ordering. Payloads and the aircraft itself are sold separately.

Adding a payload does not change the underlying flight rules. Under FAA Part 107, the remote pilot in command is responsible for safe operation of the aircraft and its payload configuration. Confirm that total takeoff weight remains within published limits and that the flight plan accounts for the reduced endurance and wind margins of a heavy-payload configuration.
