The UNITRONIC® BUS CAN 2x2x0.34 cable from Lapp is a specialized data cable for fieldbus communication in CAN- and CAN FD-based networks. It is designed for fixed installation and suitable for applications with moderate mechanical stress, where occasional movements without tensile load are permissible. The cable features a PVC outer sheath in violet color, resistant to acids and alkalis, and conditionally oil-resistant. It is suitable for use in dry and damp environments and provides excellent protection against electromagnetic interference through a copper shielding braid with high coverage (F/UTP). The UL certification according to technical specifications enables the use of the product in the North American market.

Applications

The cable is designed for industrial applications requiring reliable data transmission over CAN bus systems. It is particularly suitable for installations where the cable is to be fixed, but occasional movements without tensile stress may occur. The operating environments include dry and damp areas, although the cable is not designed for permanent immersion or extreme mechanical stress. The violet color of the PVC sheath facilitates identification in cable management.

Functions and Equipment in Detail

The cable features a construction with two pairs, each conductor having a cross-section of 0.34 mm². This configuration enables secure data transmission, especially over increasing transmission lengths. The nominal characteristic impedance is 120 Ohm, ensuring optimal impedance matching in the CAN bus network and minimizing reflections. The copper shielding braid (F/UTP) provides high protection against electromagnetic interference, securing signal integrity in industrial environments with high EMC risk.

Technology Explained Simply

The designation F/UTP describes a cable with a single shielding braid (F) around an unshielded twisted pair (UTP). This design ensures effective shielding against external interference without compromising the cable's flexibility. The PVC sheath offers chemical resistance to acids and alkalis, making the cable suitable for industrial applications. The UL certification (cUL listed) confirms compliance with safety standards of the North American market, ensuring the cable's international usability.

Compatibility and Accessories

The cable is designed for CAN- and CAN FD-based networks and can be used in systems supporting these protocols. The construction with two pairs and a nominal characteristic impedance of 120 Ohm is standard for CAN bus applications.

Installation and Mounting

The cable is intended for fixed installation and can be routed in cable ducts, trays, or along walls. Occasional movements are permitted, provided no tensile stress occurs. Installation does not require special tools, but adherence to the minimum bending radius and specified installation conditions is essential to ensure functionality. The violet color facilitates identification in cable management.

Operational Advantages

The cable offers high signal quality through the combination of twisted-pair structure and copper shielding. The chemical resistance of the PVC sheath ensures long service life in industrial environments. The UL certification expands the application range into the North American market. The construction with two pairs and a nominal characteristic impedance of 120 Ohm ensures reliable data transmission over long distances, simplifying the planning of CAN networks.
