The 6ES7194-2MH10-1AB0 is a 1-meter 24VDC power extension cable for the SIMATIC ET 200AL distributed I/O system, with angled M8 connectors at both ends and a gray PUR jacket. It connects between a module's male power output and the next device—extending the 24VDC rail without re-cabling.

When should I choose angled connectors on both ends?

Angled M8 connectors reduce the cable's stack height by approximately 13–18mm compared to straight connectors at each end. This matters in two scenarios: shallow control cabinets where the door closes within millimeters of the module face, and machine-mounted installations where the cable routes along the mounting surface rather than perpendicular to it. If your enclosure has adequate depth (50mm+ clearance from the module face), straight connectors are simpler to grip and faster to connect.

How do I identify this as a power cable—not a bus cable?

The gray jacket is the definitive visual identifier: gray = 24VDC power, green = PROFINET bus data. Never plug a gray power cable into a green bus port—sending 24VDC into a PROFINET Ethernet PHY will destroy the interface. Internally, this cable uses 4×0.50mm² unshielded conductors with PP core insulation, rated for -25°C to +80°C operation with 2 million flex cycles at a 51mm bend radius.

Frequently Asked Questions

What is the difference between this 1AB0 cable and the 1AA0 straight version?

The 6ES7194-2MH10-1AA0 is the straight-connector equivalent—same 1-meter length, same gray power conductors, but with straight M8 connectors at both ends. Choose 1AB0 (angled) when enclosure depth is tight; choose 1AA0 (straight) when clearance is adequate and ease of handling is the priority.

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

No. For module-to-module power daisy-chaining, use a plug-to-plug bus cable (note: power modules in ET 200AL use plug-to-plug cables for direct module-to-module links). This plug-to-socket extension is designed for extending an existing power run—the plug end mates with the module's output or the previous cable, and the socket end accepts the next cable's plug or a field device connector.

Is this cable suitable for outdoor installation?

Yes—the PUR jacket is UV-resistant and the IP65/IP67 rating holds when properly mated with ET 200AL M8 ports. The cable operates from -25°C to +55°C in service and withstands -30°C to +80°C during assembly.
