The 6ES7194-2MH50-1AB0 is a 5-meter 24VDC M8 power extension cable with angled plug and socket for SIMATIC ET 200AL distributed I/O. It extends the gray power rail from one module to the next at short range — the angled connectors keep the cable flat against the housing when the M8 ports sit in a tightly packed row.

Why 5 meters for a power extension?

Five meters covers adjacent modules on the same DIN rail segment or neighboring I/O blocks within one cabinet bay. It is the shortest standard length in the ET 200AL power extension lineup — enough to daisy-chain modules with clean routing, not so much that you are bundling excess cable into the duct. If the next module in the chain is in a separate enclosure or across a machine frame, step up to the 10-meter variant (6ES7194-2MN10-1AB0). The connectors and conductors are identical — the choice is purely how much reach the physical layout demands.

Angled vs. straight on a 5-meter power link

Angled connectors exit 90° to the cable — parallel to the module face. On tightly packed ET 200AL stations where I/O blocks stack close together on the DIN rail, a straight plug projects 30-40mm into the wiring duct or the module above. The angled exit stays within the module's height footprint. At only 5 meters, this cable typically stays within one cabinet section, where port crowding is most acute — making the angled choice more often the right one than on longer runs that span open trunking between cabinets.

Frequently Asked Questions

What is the difference between 6ES7194-2MH50-1AB0 and -1AA0?

The -1AB0 has angled (90°) connectors at both ends. The -1AA0 (if available in this length) has straight (180°) connectors at both ends. Both are 5m, gray, 4-pole 24VDC power extension cables. Choose angled when the port has obstructed clearance above it; straight when access is open.

Does the 5-meter length limit the number of modules on the chain?

The cable length does not limit the module count — the combined current draw of all modules and their sensor/actuator loads does. Each ET 200AL module passes power through to the next via the M8 socket. Calculate the total load on the chain and verify it stays within the M8 connector and 0.50mm² conductor ratings. For chains drawing more than the rated current, split the load across multiple power injection points fed from the 24VDC supply.
