There are a number of different standards for making networks and different devices that can be linked to one another in the industry. Use is made, inter alia, of:
• Field bus such as CanBUS,
• Wireless Ethernet.
In order to be able to use these sorts of modules reliably in the industry, the various parts must be robustly made. For this reason, M12 connectors are often used and PCBs are often treated with a special coating. This allows them to resist shocks and vibration and large fluctuations in temperature.
