What this cable is and who it’s for
The Siemens 6ES7194-2MH50-1AB0 is a preassembled power cable that connects 24 V DC to an ET 200AL remote I/O drop. Both ends come with M8 connectors — one male, one female, both angled — so you plug straight in without field-wiring the connector. The jacket is PE-PUR, halogen-free and silicone-free, which matters if the cable runs through food or pharmaceutical zones where those compounds are banned. It’s rated IP65/67 at the connectors, meaning it can take a washdown hose and still seal. Out here in the grease that’s the difference between a cable that lasts the shift and one that wicks moisture into the I/O module. Temperature range is -25 °C to 80 °C, so it won’t get brittle in a cold warehouse or soften near a hot motor housing. The cable carrier spec is 2 million bending cycles with a 51 mm bending radius at 5 m/s and 5 m/s² acceleration. If your cable rides a moving axis, that flex rating is the number you care about.
