Tilta 8V DC Male to 7-pin Nucleus-M Motor Power Cable

The Tilta TCB-7LE-DCM21 is a DC 5.5/2.1 mm (8 V) → 7-pin Lemo power cable for Nucleus-M motors. It plugs into an 8 V DC 5.5/2.1 mm output on the rig and into the motor's 7-pin power connector; further motors are then daisy-chained with Nucleus-M 7-pin → 7-pin cables. The DC plug is right-angled; colour black.

The Tilta TCB-7LE-DCM21 is the alternative to powering Nucleus-M motors from P-Tap: where the rig offers an 8 V DC output with a 5.5/2.1 mm barrel socket, this cable is all it takes and the motors run with no source of their own. One cable to the first motor, the rest linked with 7-pin cables.

DC 5.5/2.1 mm (8 V) → 7-pin Nucleus-M motor

The right-angled 5.5/2.1 mm DC plug goes into the 8 V DC output of a source on the rig — a battery plate or power module with this output. The other end is a 7-pin Lemo plug for the power connector of the Nucleus-M motor; it locks in place and will not pull out from a tug on the cable. The cable does not change the voltage; the 8 V from this output sits inside the 7.2–24 V range the Nucleus-M motors work with. If the rig only has P-Tap, the Nucleus-M P-Tap → 7-pin cable is used instead.

Daisy-chaining motors

Only the first motor is fed: from its second 7-pin connector a Nucleus-M 7-pin → 7-pin cable runs to the next motor, and that one onward the same way. Three motors thus hang on one source, and there is a single feed from the battery on the rig.

The right-angled DC plug keeps the cable along the source and does not stick out; the straight 7-pin connector sits in the motor with no bend in the cable right behind the connector.

Tilta cables

The Tilta TCB cable range links camera, battery and accessories on the rig: power from a V-Mount or Gold Mount plate over P-Tap, 2-pin Lemo, 3-pin Fischer or a DC barrel connector, USB-C PD for monitors and handles, 7-pin control cables for the Nucleus system and HDMI or BNC for the picture. Lengths follow the rig — short on the cage, longer out to arms and batteries; this cable is one of them.
