ALEXA 35 power cable compatibility with ALEXA Mini/Mini LF cables and sled-mounted battery supplies.
Note (as of October 2026)Curt O. Schaller, the developer of Artemis and Trinity, has no longer been with ARRI since the end of 2025. To our knowledge, ARRI currently has no dedicated team and no official contact persons for its stabilizer systems. In our view, the future of this line is uncertain. If you are buying new, get written confirmation from ARRI beforehand on how long service and spare parts are guaranteed. Have used rigs checked by the manufacturer before you buy.

What the thread found
- The ALEXA 35 uses the same connector type as the ALEXA Mini, but requires 24 V to start (some sources cite 28 V as nominal voltage), while many Mini/Mini LF cables are wired for 12 V and will not initiate power-up; incorrect wiring does not damage the camera, it simply fails to start.
- A 24 V cable functions on ALEXA Mini and Mini LF (ARRI recommends 24 V for those models anyway), but on sled-mounted systems this prevents hot-swapping batteries via 24 V auxiliary supplies, for example on PRO-Sleds the AUX battery cannot be used, and on Tiffen M1/M2 rigs at least three batteries are required.
- According to cable manufacturers, correct wiring connects camera pins 2, 3, 4 to ground and pins 6, 7, 8 to the sled's 24 V output; most 24 V-capable sleds provide separate pin groups for 12 V and 24 V outputs.
- ARRI Artemis 1 and Trinity 1 units sometimes lack separate 12 V and 24 V pins (some units were retrofitted to 24 V later), allowing the same cable across platforms, whereas Tiffen-brand sleds require a cable specifically wired for 24 V.
- The ALEXA 35 power socket is angled; right-angle connectors are recommended to avoid strain.
- Cage-mounted 6-pin power connectors (for example Tilta-style systems) are wired for 12 V only and require a different cable.
- The ALEXA 35 is light enough to run from an onboard battery, bypassing sled-based power entirely.
Depends on
- Whether all 24 V-capable sleds have separate 12 V and 24 V pin groups (ARRI Artemis 1 and Trinity 1 noted as exceptions).
- Whether 24 V or 28 V is the correct nominal voltage specification for the ALEXA 35.
