The 6ES7194-2LN10-1AC0 is a 10-meter ET 200AL power cable with a factory-assembled straight M8 socket on one end and open leads on the other. It brings 24 V DC from the last module in a power chain to a terminal block, sensor, or actuator—cut to length and terminated on site. At 10 meters, it is sized for within-zone distribution: everything stays in the same cabinet line-up or the same row.

10 meters vs 15 meters—when is the shorter length the right call?

At 10 meters, the voltage drop at full 4 A load is about 0.7 V—roughly 30% less than the 15-meter variant. This gives the 10 m cable more headroom when the 24 V DC source is already near the lower end of its tolerance band. Just as importantly, 10 meters of cable is easier to dress inside a single cabinet or between adjacent enclosures in the same line-up. There is less slack to coil, fewer cable ties, and a cleaner wireway. Choose 10 m when the distance from the ET 200AL block to the power termination point is comfortably under 10 meters—the majority of within-cabinet and adjacent-cabinet installations. Choose 15 m when the power source or the field device is in a different row, across a walkway, or in a separate enclosure group.

Socket-to-open-end vs plug-to-open-end—what does the connector gender decide?

The socket end mates with a male M8 plug—the output connector of an upstream module or the plug of the previous cable in the power chain. This makes the 1AC0 a continuation cable: it extends an existing power run to a termination point. If you are starting a new run directly from a module's output socket, a plug-to-open-end cable (like the bus 0AC0) may be the cleaner choice—its plug inserts directly into the module, and the open end delivers power downstream. In ET 200AL power chains, however, the standard extension topology is plug-to-socket, and the open-end variant is for runs that end at a terminal block rather than another M8 connector.

What are the installation steps for the open end?

The four cores are color-coded white, brown, blue, and black—matching the standard ET 200AL power pinout. At the termination point, strip the gray PVC jacket, strip each core, and land them on the corresponding terminals. No special crimp tool is required for the field end—standard screw-terminal or spring-clamp connections accept the 0.50 mm² conductors directly. The M8 socket end is factory-molded and must not be cut. Test continuity before applying power—a single swapped pin can put 24 V on a 0 V rail and damage every module in the chain.

Frequently Asked Questions

How does this differ from the 1AA0 and 1AB0 10-meter power cables?

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, for daisy-chaining modules). The 1AB0 is the angled version of the 1AA0 (90° connectors for tight clearance). This 1AC0 is the field-termination variant: one pre-assembled M8 socket, one open end. Choose 1AC0 when the power chain ends at a terminal block; choose 1AA0 or 1AB0 when it continues to another M8-equipped device.

Is this power cable shielded?

No. Gray jacket = unshielded 24 V DC power. Shielding is unnecessary at DC and would add cost and stiffness. Only green-jacket bus cables carry the PROFINET dual shield. ET 200AL enforces this distinction with color coding—gray power and green bus must never be cross-connected.

Can I use this cable outdoors?

The IP65/IP67 rating handles rain and temporary immersion, but the PVC jacket will degrade under prolonged direct sunlight. For outdoor installations, PUR-jacketed cables (2MN series) are the better choice—they resist UV and remain flexible at low temperatures. If the cable is inside an outdoor-rated enclosure or shaded cable tray, PVC is acceptable.
