Ethernet for industrial environment

The harsh environments of plants and workshops put much more stress on the components than the office environment does: Dust, moisture, chemicals, mechanical stress, extreme temperatures and much higher electromagnetic interference lead to specifications which were unknown and unrivalled in the past. At the same time, plants and workshops demand highest possible reliability and availability, as even short service interruptions lead to high losses.

One hour downtime of a PC in an office is annoying; one hour downtime of a production line is not acceptable as it inevitably means losing enormous amounts of money. Especially in the industrial environment quality and reliability of the components – above all outlets and connectors – are exceptionally important and in most cases mission-critical. So it’s no wonder that for industrial applications different standards apply, e.g. ISO/IEC 24702 for the cabling and IEC 61076-3-106 for the connectors

Protection class

In addition to the quality of carefully coordinated components, protection against solid and liquid substances is also important in industrial applications. The international standard IEC 60529 defines the IP code (International Protection) as a simple designation system: the first digit indicates protection against the ingress of solid bodies such as dust, the second digit indicates protection against water / moisture.
