The Siemens 6ES7194-2LH50-1AC0 is a 5-meter flexible power cable for ET 200AL, pre-assembled with a 4-core M8 female connector and rated for continuous flexing — 2.5 million bending cycles at 52 mm radius, 3 m/s, 10 m/s², with IP65/67 protection.
What the ratings mean in the field
The -40 to 80 °C range covers outdoor freezer bays and hot cabinet interiors. The silicone-free cable sheath avoids contamination in paint booths or potting processes — a detail that matters if your panel goes into automotive or electronics assembly. PVC outer sheath and PP core insulation give decent chemical resistance for most industrial environments, but watch the bend radius: the minimum single-bend radius is 26 mm, and for repeated flexing you need at least 52 mm. Inside a cable tray or drag chain, that governs how tight you can route it. The 4-core conductor (0.5 mm² each, wire colors white/brown/blue/black) matches the standard ET 200AL power wiring scheme — two cores for supply, two for return. The cable is factory-tested and comes with a 180° outlet M8 female that threads directly onto the module's power port.
