Atomos ATOMFLEX PRO HDMI 2.0 Coiled Cable

This Atomos coiled cable is built for video professionals who need a tidy, reliable HDMI link on camera rigs or external monitors. The full-size connectors lock securely and the coil extends when extra reach is required. It suits creators working with HDR-capable recorders and 4K 60p workflows.

Coiled Design and Die-Cast Connectors

The coiled construction stretches from 30cm up to 60cm, letting you reposition a monitor without cable slack. Die-cast metal shells add rigidity at the plug ends, reducing strain on ports during handheld or gimbal work. This physical flexibility keeps the rig clean while maintaining a solid signal path.

4K 60p 10-bit at 18Gbps Headroom

The cable carries 4K 60p 10-bit HDR video at the full 18Gbps bandwidth allowed by the HDMI 2.0 specification. It handles 4K 30p 10-bit without issue, but cannot support higher frame rates or bit depths that exceed the 18Gbps ceiling. Builders needing 4K 120p or 8K throughput should select a different cable class.

Questions about this item

Will the coiled HDMI 2.0 cable need replacement if I regularly extend it beyond the 60 cm maximum?

The cable is rated to extend from 30 cm up to 60 cm; staying within that range avoids stress on the die-cast connectors and the internal 18 Gbps conductors.

What is the first limit reached when running 4K 60p 10-bit video continuously through this cable?

The 18 Gbps bandwidth ceiling is the hard limit; 4K 60p 10-bit uses the full pipeline, so any longer run or tighter bend that degrades signal integrity will show errors first.

Does the cable generate noticeable heat or require extra power during all-day 4K HDR transmission?

It is a passive copper cable with no active electronics, so it draws no external power and produces no measurable heat even at the full 18 Gbps rate.
