chainflex CFBUS-PVC Bus Cable

High Durability Chain Cable for Industrial Applications with Medium Mechanical Load

The chainflex CFBUS.PVC.020 CAN-bus cables manufactured by igus are industrial control cables designed for use in energy chains (Energy Chains), featuring many specialized characteristics. These cables are designed for machines and systems in motion that require high-speed network communication (such as CAN-Bus). The cable consists of two twisted wires covered with strong shielding to prevent electromagnetic interference (EMC). The PVC outer jacket is specifically made to be flexible, abrasion-resistant, and suitable for energy chain applications, meaning it is ideal for environments where the cable must continuously bend and straighten.

Technical Specifications for the Moving Cable CFBUS-PVC001

The chainflex CFBUS.PVC.020 is an industrial bus cable with a fine copper conductor (class 6) in accordance with DIN EN 60228, featuring a twisted pair of wires (1x2xAWG22) with a cross-sectional area of 0.34 mm². The wires are purple with a white-brown stripe, without numbering. The wires are twisted and have a foil aluminum shield and a braided copper shield with approximately 90% coverage to provide strong electromagnetic protection. The outer jacket is made of a special PVC formulation (CF.PVC) in purple (RAL 4001). The outer diameter of the cable is approximately 6.5 mm. The conductor resistance is a maximum of 57 ohms per kilometer, and the insulation resistance is at least 1 GΩ×km at 20°C. The capacitance is 30 nF/km, and the signal transmission resistance is a maximum of 110 ohms. The cable can operate in temperatures from -5°C to +70°C in static applications and -5°C to +70°C in flexible applications. It is halogen-free, made without special PVC or silicone, and is resistant to biodegradable hydraulic oils and complies with flame resistance tests IEC 60332-1-2. The minimum bending radius in energy chain movement is 10 times the outer diameter of the cable (about 65 mm), making it suitable for dynamic applications with continuous movement in energy supply systems.
