What this cable connects
The Siemens 6ES7392-4BF00-0AA0 is a factory-terminated connecting cable for S7-300 64-channel I/O modules, 5 m long, shipped two per packing unit. It mates the module front connector to the field wiring — no field termination, no splice point to corrode in a steam-heavy mill environment.
Environmental limits for the cable assembly
Rated for an ambient operating range of 0 °C to 60 °C. That 60 °C ceiling keeps the cable jacket and insulation within spec inside a crowded, warm cabinet — no derating needed below that, but exceeding it risks embrittlement over time.
