The 6ES7194-2MH03-1AB0 is an ultra-short 0.3-meter 24VDC power extension for the ET 200AL system, with angled M8 plug to angled M8 socket and a gray PUR jacket. At 300mm, it is built for the shortest practical jump between adjacent modules on the same DIN rail.

Why choose 0.3 meters over 1 meter?

Within a single enclosure, adjacent ET 200AL modules are typically spaced 50–150mm apart. A 0.3-meter cable bridges that gap with minimal excess—no coil to manage, no loop to cable-tie, no slack to interfere with the door. In a dense I/O station with eight modules side by side, eight 0.3m extensions produce a cleaner panel than eight 1m cables bundled and folded. The 1m length becomes the right choice only when spanning between two separate enclosure sections.

Angled at both ends—same reasoning, shorter cable

The angled connectors save 13–18mm of stack height at each end compared to straight M8. In a shallow control cabinet where every millimeter between the module face and the door counts, this 0.3m angled extension delivers both the shortest cable length and the lowest installed profile in the ET 200AL power cable range.

Frequently Asked Questions

Is 0.3m the shortest power extension available?

No. Siemens also offers a 0.19m variant (6ES7194-2MH02-1AA0) for applications where the modules are mounted immediately adjacent with no separation. The 0.3m provides a slight margin for modules that are close but not butt-to-butt.

Can I use this for the bus connection instead of power?

No. The gray jacket and unshielded construction identify this as a 24VDC power cable. For bus connections at 0.3m, use the green-shielded 6ES7194-2MH03-0AA0 (straight) or 6ES7194-2MH03-0AB0 (angled).
