This is particularly advantageous with different networks and cramped spaces. When used in railway engineering, for example, the network communication comprising control, climate and light could be coded in one colour, the network of surveillance cameras in another, and the infotainment with the WiFi for passengers in a third colour. In this way, each connector can be assigned particularly quickly, which greatly facilitates system maintenance and repair. These practical coloured coding rings are also helpful in other areas with adjacent interfaces.
Let yourself be convinced by the simple snap-in assembly, and keep track of everything!
