A 15-meter M8 straight-socket to open-end power cable purpose-built for SIMATIC ET 200AL distributed I/O nodes. The gray PUR jacket identifies it as a power supply cable within the ET 200AL cabling system—gray for power, green for bus data. Shielded construction with aluminum-clad foil and tin-plated copper braid ensures signal integrity even in electrically noisy cabinets.

How does the ET 200AL color-coding system work?

Siemens uses jacket color to distinguish cable functions in the ET 200AL ecosystem: green cables carry PROFINET bus data between I/O nodes, gray cables supply 24VDC power. Both cable types use the same M8 4-pole connector form factor—color is the visual differentiator that prevents misconnection during commissioning and troubleshooting.

What does the shielding protect against?

The dual-layer shield (aluminum-clad foil plus tin-plated copper braid) attenuates both high-frequency EMI from VFDs and motor cables and low-frequency noise coupled from adjacent power conductors. In ET 200AL installations where power and bus cables share the same cable carrier, the shield prevents crosstalk that could corrupt PROFINET frames or cause spurious sensor readings.
