What this cable is and where it runs
The Siemens 6ES7194-2LH50-0AB0 is a factory-assembled bus cable for connecting ET-CONNECTION nodes — specifically the SIMATIC ET 200AL family — in IP65/67 distributed I/O drops. It comes terminated at both ends with 2x M8 angled plugs, 4-pin, shielded, in a 5 m length. That means you pull it from the junction box to the field device without crimping or field-wiring the connector; the shield is factory-terminated inside the overmold. The cable construction is 2Y(ST)CY 1x4x0.5/1.0-100-GN: four PE-insulated cores (0.5 mm inner conductor, 1 mm core insulation) with an overlapped aluminum-clad foil and a tin-plated copper braid, all inside a green PVC sheath. The shield design — foil plus braid — gives you both 100% coverage for radiated noise and mechanical toughness in cable-carrier applications.
Temperature range and washdown survival
The IP65/67 rating means the M8 connectors and the cable jacket survive washdown — suitable for food-and-bev lines, packaging floors, or any zone where you hose down the I/O. The PVC sheath is not halogen-free, so check your plant's fire-smoke requirements; it is silicone-free, which matters if you're potting or bonding nearby.
Cable-carrier rating — 1 million bending cycles
This cable is certified for 1,000,000 bending cycles in a cable carrier at a bending radius of 100 mm, travel speed of 4 m/s, and acceleration of 4 m/s². For single bends the minimum radius drops to 20 mm; for multiple bends it's 40 mm. If you're routing through a drag chain on a gantry or a moving robot dress-pack, the 1M-cycle rating gives you a solid service-life baseline before replacement.
