The 6ES7194-2LN10-1AA0 is the standard 10-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. It is the first cable most engineers reach for when extending a 24 V DC power chain within a single cabinet line-up or between two adjacent enclosures.

Why is 10 meters the default choice for power extension?

Ten meters covers the vast majority of within-zone power distribution scenarios: the full length of a multi-bay cabinet line-up, from one end of a machine frame to the other, or from the control cabinet to a nearby junction box. It is long enough to be useful, short enough to dress cleanly without coiling. Voltage drop at full 4 A load is about 0.7 V—comfortably within the ±10% tolerance band of 24 V DC industrial electronics. For runs that genuinely need more reach, the 15-meter variant (2LN15-1AA0) adds five meters at a proportional cost; for runs where everything is inside one cabinet, the 2M PUR short-length series (0.19 m–1 m) keeps cabling minimal.

Straight vs angled—why keep it simple?

Straight connectors are the default because most enclosures have adequate overhead clearance above the M8 ports. They are easier to grip during installation, easier to unplug during maintenance, and cost slightly less than angled equivalents. If your panel has at least 30 mm of space above each M8 port—the plug body height plus the cable's single-bend radius—the straight 1AA0 is the right call. If overhead clearance is tight and the cable must exit flat against the module face, the angled 1AB0 is the alternative.

How does this compare to the 2LN15-1AA0?

Identical in every respect except length. Same gray PVC jacket, same 4 × 0.50 mm² PP-insulated cores, same straight M8 plug and socket, same IP65/IP67 rating, same factory pre-assembly at both ends. The 2LN10-1AA0 is 10 meters; the 2LN15-1AA0 is 15 meters. The 10-meter variant gives better voltage drop margin, costs less, and leaves less slack to manage. Choose it unless the physical distance between the power source and the first module genuinely exceeds 10 meters.

Frequently Asked Questions

Can I shorten this cable if 10 meters is too long?

Technically yes—both ends are pre-assembled, but the cable can be cut mid-span and the plug end re-terminated at a terminal block. However, doing so wastes the factory pre-assembly you paid for. A cleaner approach is to order the correct length from the start: 2M PUR short-length cables (0.19 m–1 m) for within-panel runs, 2LN10 (10 m) for within-zone, or 2LN15 (15 m) for inter-cabinet. If only the field end needs custom length, the 1AC0 socket-to-open-end variant is purpose-built for that job.

What is the difference between 1AA0, 1AB0, and 1AC0 in the 2LN10 series?

All three share the same 10 m gray PVC, 4 × 0.50 mm², IP65/IP67 construction. The 1AA0 is a straight plug-to-socket extension (both ends pre-assembled). The 1AB0 is the same but with angled connectors for tight clearance. The 1AC0 is socket-to-open-end for field termination. Choose 1AA0 for standard extension, 1AB0 when overhead clearance demands 90° exits, and 1AC0 when the power run ends at a terminal block.

Is this cable shielded?

No. Gray jacket signals unshielded 24 V DC power. Only green-jacket bus cables include PROFINET-grade dual shielding. The color-coding is mandatory reading for every ET 200AL installer—cross-connecting gray power into a green bus port can destroy the PROFINET interface.
