Cable Jacket Colors per DESINA
Cable jacket materials are available in many colors. The machine tool industry has adopted a standard referred to as DESINA, that aims to standardize cable colors and their interconnection into one common platform for machine tools and manufacturing systems. DESINA is short for (DEcentralized and Standardized INstAllation Technology. The purpose of this standard is, that maintenance personnel can easily identify cable runs and their purpose, even across different machine suppliers. This standard was initially developed for the automotive manufacturing industry and is widely used in motion control applications and machine tools.
As per this standard the following jacket colors are used for the respective applications.
Orange, RAL 2003: servo power, frequency-controlled devices, shielded Green, RAL 6018: measurement cable such as measuring systems, feedback systems, analog sensors, shielded Purple, RAL 4001: fieldbus and hybrid field bus, shielded Yellow, RAL 1021: actuator/sensor cable, not shielded (ASi) Black, RAL 9005: power output, not shielded Gray, RAL 7040: multiwire control cable for control voltages and 24 V technology, not shielded
The RAL color code uses a number coded system to define the shade. There can sometimes be a slight shade difference between manufacturers and even between production lots from the same manufacturer.
Sometimes slight deviations from the standard can be found. For example, control cables for voltages greater than 24V are often gray or black, servo feedback cables may be orange, many shielded motor-supply cables as well as power tray cables are commonly made with black jackets.
