The 6ES7194-2LH50-1AB0 is a 5-meter 24VDC power extension cable with angled connectors at both ends: an M8 plug (male) at one end and an M8 socket (female) at the other. It extends an existing ET 200AL power chain—the plug inserts into a module output or the socket of the previous cable, and the socket receives the plug of the next cable or module input. The gray PVC jacket and unshielded 4 Li9Y 0.50mm² construction match the rest of the ET 200AL power cable family.

When should I choose the angled power extension over the straight variant?

The decision turns on vertical clearance above the M8 port. Angled connectors exit horizontally and need roughly 12mm of headroom; straight connectors extend about 30mm above the port before the cable bends. If the ET 200AL modules are installed in a shallow IP65/67 machine-mounted enclosure—or if wire duct runs directly above the DIN rail—the angled variant is the difference between closing the lid and re-engineering the panel layout. The trade-off is minor: angled plugs are slightly less convenient to grip during installation but perform identically once seated.

How does the 5-meter power extension compare to the 10-meter and 15-meter versions?

Same plug-to-socket topology, same 4 Li9Y construction—only the length changes. The 5-meter (2LH50) is the shortest standard power extension in the ET 200AL M8 family, built for adjacent modules or modules spaced within a single cabinet. If you need to span multiple cabinets, step up to the 10-meter (2LN10-1AA0/1AB0) or 15-meter (2LN15-1AA0/1AB0) variants. Choosing the right length from the start avoids coiling excess cable inside the wire duct—cleaner panel, faster installation.

Why does the gray jacket matter?

In the ET 200AL M8 ecosystem, jacket color is a safety-critical signal. Gray identifies an unshielded 24VDC power cable; green identifies a shielded PROFINET bus cable. The M8 connector is physically identical across both—4 pins, same pitch, same keying. Plugging a gray power cable into a green bus port sends 24V into the PROFINET ASIC and destroys the interface. The gray jacket is your visual lockout: if the cable in your hand is not gray, do not plug it into a power port. This rule is non-negotiable in every ET 200AL installation.
