What it does
The 6ES7194-2MH03-0AB0 is a preassembled flexible cable with 2x M8 plugs (angled, 4-pin, shielded) for connecting SIMATIC ET 200AL distributed I/O nodes in IP65/67 environments. The 0.3 m length suits close-coupling between a junction and a sensor actuator box. The PUR sheath resists oils and coolants, and the cable is halogen- and silicone-free, which matters for clean-room or food-area installations where outgassing or contamination is a concern.
Temperature range and bend life
Rated for storage at -40 °C and exposure up to 80 °C, so it tolerates heat near a motor or cold storage handling. The cable is rated for 1 million bending cycles at 100 mm radius, 4 m/s travel, 4 m/s² acceleration — suitable for cable carrier use on moving gantries or robot dress packs. For static installation, a single bend radius down to 20 mm is permitted.
Shield design and signal integrity
The shield is an overlapped aluminum-clad foil plus a braid of tin-plated copper wires — a construction that handles both low-frequency magnetic interference (braid) and high-frequency capacitive coupling (foil). That makes it a fit for noisy industrial environments with drives or inverters close to the communication line.
