What it is and where it fits
The 6ES7194-2LH20-0AB0: This is a preassembled flexible cable for connecting ET-CONNECTION nodes — specifically SIMATIC ET 200AL I/O modules in IP65/67 enclosures. Both ends carry an angled M8 4-pin plug, shielded for noise environments. The 2 m length is the backbone for distributed I/O drops where you need a factory-assembled, tested link rather than field-terminated cable.
Rated for tough environments
Operating temperature span is -40 to 80 °C, so it can live in a freezer bay or near a hot motor junction box. Assembly temperature is -30 to 80 °C — plan your install accordingly. Silicone-free construction matters for paint shops or coating lines where silicone outgassing ruins adhesion. Not halogen-free, so verify local smoke toxicity requirements. Rated for 1 million bending cycles at 100 mm bend radius, 4 m/s speed, 4 m/s² acceleration — a genuine drag-chain cable. For single bends, minimum radius is 20 mm; for multiple bends, 40 mm.
Construction and handling
Shield is overlapping aluminum-clad foil plus a braid of tin-plated copper — that is the standard 2Y(ST)CY construction, giving both electrostatic and electromagnetic screening. Core colors are white / yellow / blue / orange. PVC sheath, green, 5 mm outer diameter. Preassembled at both ends — no crimping, no continuity check needed. The 90-degree outlet on the connector keeps the cable profile low against the module faceplate.
