Differences between Signal and Control Cables
1. Introduction
From the outside, signal cables and control cables do not seem to be very different from each other. Both types of cables have plural cores, and both seem to be used as carriers for transmitting signals. But what is the difference between these two types of cables? Next let me give you a brief description of the difference.
2. What is a Signal Cable
Generally speaking, signal cables are used to transmit signals from sensors, computers, and measuring devices. These cables have a relatively small outer diameter and are shielded or pairs of cables to prevent electromagnetic signal interference from the outside world. Common types are: LiYY, LiYY-TP, LiYCY, LiYCY, LiYY-TP, LiYCY, LiYY-TP, LiYCY.
3. What is Control Cable
Generally speaking, control cables are used as connecting wires, measuring, testing and control cables in machine tool manufacturing, plant engineering and assembly lines. These cables are more suitable for automation applications in industrial production and are usually equipped with a yellow-green ground wire, the voltage of these cables is higher than that of signal cables. Common types are: YSLY, YSLCY, YY, CY
4. Key Differences Between Signal and Control Cables
| Cable Size | Voltage | Application | |
| Control Cable | 0.5mm2~2.5mm2 | Up to 750V | Machine,Plant, Production lines |
| Signal Cable | 0.14mm2~1.5mm2 | Up to 500V | Computer, Electronic, Sensor |
Industrial Automation system
5. How to Choose the Right Cable for Your System
- A. First, please determine the voltage and current, so that you can determine the size of the cable.
- B. Secondly, please determine whether the cable will have temperature, flexibility, abrasion resistance, chemical resistance, UV resistance and other requirements. So that you can choose a suitable cable insulation and jacket material.
- C. Finally, I recommend that you contact the relevant experts for advice if possible, KMCABLE has a technical team with more than 12 years of experience to help you, so please feel free to contact us if you need help.
6. Conclusion
Control cables and signal cables may look similar, but their actual application environments are very different. It is recommended to use control cables if they are to be used in industrial production processes. These cables are larger in size, more stable in signal transmission and can withstand higher voltages.
