ETHERNET IN INDUSTRIAL USE

ProfiNET IO specifies various connectors for data transmission. distinguishing feature is the protection class, i.e. the distinction between “inside” and “outside”. RJ45 (copper, IP20) and LC connectors (optical, IP20) as well as M12 D-coded and X-coded connectors (copper, IP67).

based on the Ethernet standard and uses either two or four wire pairs. Precise requirements in terms of the cables to be used, braided shield and pair foil shield, specific external diameters and two relatively large wire cross-sections (typically AWG22 with two pairs and AWG23 with four pairs). Three application types: 1. Permanently installed, no movement, green outer sheath 2. Flexible (typical patch cable), occasional movement/vibration, green outer sheath 3. This includes special applications such as cables for highly flexible use (FD or torsion) as well as cables for permanent installation with a black outer jacket
