The UNITRONIC® BUS LD 3x2x0.22 cable from Lapp is a flexible data cable designed for fixed installation, intended for use in industrial bus systems. The cable features PVC insulation in violet colour and is suitable for use in dry and damp rooms. It serves as a transmission medium for various bus systems based on RS 485 and RS 422 standards, such as Modbus, SUCOnet P, Modulink P, or VariNet-P. The cable is designed for maximum EMC shielding effectiveness to minimise interference during operation and ensure reliable data transmission.

Applications

The cable is specifically designed for industrial applications where stable and interference-free data communication is required. It is used in systems that communicate via serial interfaces, particularly in automation systems, building automation technology, and industrial control systems. Its suitability for use in dry and damp rooms makes it flexible for various environments without performance degradation due to high humidity.

Functions and Features in Detail

The UNITRONIC® BUS LD 3x2x0.22 features a construction with three conductors, each consisting of two individual wires with a cross-section of 0.22 mm². This configuration enables efficient data transmission while providing mechanical stability. The PVC insulation ensures sufficient electrical insulation and mechanical protection. The violet colour facilitates visual identification and simplifies installation and maintenance within the network.

Technology Explained Simply

The cable is designed for fixed installation, meaning it is not intended for frequent movement or bending, but for permanent installations in machines, plants, or buildings. The maximum EMC shielding effectiveness protects data transmission from electromagnetic interference originating from other electrical devices or cables. This is particularly important in industrial environments where many electrical and electronic components operate simultaneously. The use of RS 485/RS 422 technology enables serial communication over long distances with high reliability.

Compatibility and Accessories

The cable is compatible with various bus systems based on RS 485 and RS 422, such as Modbus, SUCOnet P, Modulink P, and VariNet-P. These systems are commonly used in automation technology to connect devices and exchange data. Using the UNITRONIC® BUS LD 3x2x0.22 ensures proper integration into existing or newly constructed networks of this type.

Installation and Mounting

Installation is intended for fixed routing, and the cable is not designed for frequent movement or bending. The violet colour aids identification during installation. The PVC insulation provides sufficient mechanical and electrical protection. The cable is suitable for use in dry and damp rooms, enabling broad applicability in various industrial environments.

Operational Advantages

The maximum EMC shielding effectiveness ensures stable data transmission, even in environments prone to interference. The use of RS 485/RS 422 technology enables reliable communication over long distances. The flexible construction facilitates installation, while the PVC insulation and violet colour support handling and identification. The cable is suitable for a wide range of bus systems, increasing its application flexibility.
