What cable does DeviceNet use?

1, Cable type and specifications
The topology structure of DeviceNet networks usually adopts the form of trunk and branch cables, so cables are correspondingly divided into two types: trunk cables (thick cables) and branch cables (thin cables).
Trunk cable (thick cable)
Specification: Generally 2X18AWG+2X15AWG. This specification of cable can withstand higher current and signal transmission requirements, making it suitable as a connecting cable in backbone networks.
Characteristics: Coarse cables have high conductivity and physical strength, which can support long-distance data transmission and high data transmission rates. At the same time, its shielding effect is also better, which can effectively resist electromagnetic interference in industrial environments.
Branch cable (thin cable)
Specification: Generally 2X24AWG+2X22AWG. Thin cables are used to connect individual devices or smaller groups of devices, and their specifications are small, making it easy to lay cables in small spaces.
Characteristics: Although the specifications of the thin cable are relatively small, it still has good electrical performance and shielding effect, which can meet the data transmission needs in branch networks.
2, Cable structure and materials
The structure and material design of DeviceNet cables fully consider the particularity of industrial environments to ensure their stable operation.
Conductor material: Multiple strands of tinned copper wire are usually used as conductors to improve conductivity and corrosion resistance.
Insulation material: Power line pairs usually use PVC (polyvinyl chloride) as the insulation material, while data line pairs may use high-performance materials such as physically foamed PE (polyethylene) to improve the stability and anti-interference ability of data transmission.
Shielding layer: The DeviceNet cable adopts a dual shielding structure of aluminum foil wire pair shielding and external 90% coverage tinned copper wire braided shielding to effectively resist electromagnetic interference and radio frequency interference.
Outer sheath: The outer layer of the cable is covered with flame-retardant PVC or PUR (polyurethane) and other weather resistant materials as an outer sheath to protect the cable from physical damage and chemical corrosion.
3, Cable performance characteristics
The DeviceNet cable, with its unique structure and material design, has the following performance characteristics:
Strong anti-interference ability: The dual shielding structure can effectively resist electromagnetic interference and radio frequency interference in industrial environments, ensuring the stability and reliability of data transmission.
Long transmission distance: Designed with low transmission loss, it can achieve long-distance data transmission and meet the actual needs of industrial sites.
High transmission rate: The high-quality transmission medium and standardized interface design enable DeviceNet cables to support high data transmission rates, meeting the real-time requirements of industrial control systems.
Good compatibility: The standardized interface design and communication protocol enable DeviceNet cables to seamlessly connect and communicate with various types of devices.
High reliability: High quality manufacturing processes and material selection ensure the reliability and stability of DeviceNet cables, which can also operate stably for a long time in harsh industrial environments.
4, Application scenarios
DeviceNet cables are widely used in various device connections and communication scenarios in the field of industrial automation, such as connecting sensors, actuators, controllers, and other devices to achieve data exchange and control between them. DeviceNet cables play a crucial role in production lines, robot systems, automated warehouses, and other applications.
