What it is and what it does
The Siemens 6ES7194-2MH20-0AA0 is a pre-assembled bus cable for connecting ET-CONNECTION nodes such as SIMATIC ET 200AL in environments requiring IP65/67 protection. It is shielded, halogen-free, and silicone-free, with a 2-meter length and M8 4-pin plugs on both ends. Rated from -40 to 80 °C and constructed with PUR jacket, it withstands washdown zones, cold storage, and hot factory bays. The cable carries a 1-million-bending-cycle rating for cable-carrier use at 100 mm bend radius, 4 m/s, and 4 m/s² acceleration.
Integration and routing
The cable uses a 180° cable outlet and has an outer diameter of 5 mm with a minimum single-bend radius of 20 mm and a multiple-bend radius of 40 mm. Core insulation is PE, and the shield is an overlapped aluminum-clad foil plus a braid of tin-plated copper wires — effective against EMI to 30 MHz. For cable-carrier routing, keep bends above 100 mm radius and acceleration under 4 m/s² to reach the full 1 million cycles. The GREEN PUR sheath simplifies identification in dense wireways.
