The 6ES7194-2LN15-1AA0 is the standard 15-meter power extension cable for ET 200AL—straight M8 plug on one end, straight M8 socket on the other, gray PVC jacket, both ends pre-assembled and ready to plug in. It is the workhorse of the 2LN power cable family: no special angles, no field termination, just a clean extension from one module to the next or from the cabinet to a remote I/O block.

Straight vs angled—why choose this over the 1AB0?

The straight connectors exit inline with the cable—perpendicular to the module port face. This is the simplest routing path when the enclosure has at least 30 mm of clearance above the port for the connector body plus bend radius. In a deep enclosure with the cable tray above or below the DIN rail, straight is the natural choice. Choose 1AB0 (angled) when the lid, wireway, or adjacent module leaves less than ~30 mm above the port—the 90° exit routes the cable flat along the module face instead of straight up. If clearance is not a constraint, the straight 1AA0 is easier to route, easier to grip during installation, and slightly less expensive.

How does this 15-meter cable compare to the 10-meter 2LN10-1AA0?

Same connector configuration, same jacket (gray PVC), same core construction (4 × 0.50 mm², PP insulation), same IP65/IP67 rating. The only difference is five extra meters. Choose 15 m for inter-cabinet runs, across-the-room distribution, or when the 24 V DC source and the ET 200AL block are in different enclosures. Choose 10 m when everything lives within the same cabinet line-up or a single row. For voltage drop at full load, the 10 m variant gives slightly more headroom—but at typical ET 200AL loads both are well within tolerance.

What does pre-assembled at both ends mean for the installer?

No stripping, no crimping, no soldering, no pinout errors. Both M8 connectors are molded at the factory and tested as a complete assembly. The plug inserts into the upstream module's power output or the previous cable's socket; the socket receives the next cable's plug. For volume panel builders, this eliminates the most labor-intensive step of field wiring and removes the most common source of commissioning faults—miswired DC pins that take hours to trace.

Frequently Asked Questions

Can I connect this directly between two ET 200AL modules?

It depends on the module's power connector gender. ET 200AL power modules typically have female M8 output sockets. This plug-to-socket cable extends from a module's output—the plug inserts into the module, and the socket continues the chain to the next cable or device. For direct module-to-module bridging where both sides present female sockets, use a plug-to-plug power cable (available in the 2M PUR short-length series for within-panel module connections). This cable is an extension, not a bridge.

What is the difference between 1AA0, 1AB0, and 1AC0 in the 2LN15 power series?

All three share the same 15 m gray PVC construction. The difference is connector configuration: 1AA0 is straight plug to straight socket (standard extension), 1AB0 is angled plug to angled socket (tight-clearance extension), and 1AC0 is straight socket to open end (field termination). Choose 1AA0 for general-purpose extension, 1AB0 when overhead clearance is tight, and 1AC0 when the power run ends at a terminal block rather than another M8 connector.

Is this cable suitable for outdoor installation?

The IP65/IP67 rating handles rain and temporary immersion, but the PVC jacket degrades under prolonged UV exposure. For outdoor installations with direct sunlight, PUR-jacketed cables (2MN series) are the better choice—they resist UV and maintain flexibility at low temperatures. For outdoor cable trays that are shielded from direct sun, PVC is acceptable.
