The 6ES7194-2MH02-1AA0 is the shortest power extension cable in the ET 200AL range at just 0.19 meters—essentially a power jumper for modules mounted immediately adjacent on the same DIN rail. Straight M8 plug to straight M8 socket with a gray PUR jacket.

When is 0.19 meters the right choice?

When two modules are mounted butt-to-butt—no space between their housings—the gap between power ports is roughly the width of two connector bodies plus a few millimeters. A 0.19m cable bridges exactly that gap. There is no shorter factory-assembled option. If the modules have even 50mm of separation, step up to the 0.3m variant (6ES7194-2MH03-1AA0) for a less stressed cable run.

Gray jacket, straight connectors—what is the engineering rationale?

At 0.19m, the cable has almost no routing flexibility—the connectors must be straight because the cable body is barely longer than the connector shells themselves. Angled connectors on a sub-200mm cable would force an unnatural twist into the short conductor section. The gray jacket and unshielded 4×0.50mm² construction confirm this is a 24VDC power-only cable—never use it on a green bus port.

Frequently Asked Questions

Is the 0.19m length measured end-to-end or connector tip to connector tip?

Siemens specifies cable length as the flexible cable body between the two overmolded connector housings. The overall tip-to-tip dimension is slightly longer due to the M8 connector shells.

Can I use this cable in a cable track?

No. At 0.19m, the cable body is too short to absorb flexing. This cable is designed for stationary within-enclosure wiring only. For moving applications, use a minimum 1m cable to accommodate the required bend radius.
