The UNITRONIC® BUS PB FC 1X2X0.64 bus cable from Lapp is a data cable designed for fixed installation in industrial applications, particularly in PROFIBUS DP networks. The cable is manufactured as a Fast Connect (FC) cable, enabling quick and reliable connections with compatible connectors. It features a nominal characteristic impedance of 150 Ohm, which is essential for stable data transmission in bus systems. The cable is insulated with PVC and is available in violet, facilitating easy identification within cable harnesses. The outer diameter measures 8 mm. The cable construction is suitable for use in dry and damp environments and provides maximum EMC shielding to minimize interference from electromagnetic fields. The UV resistance of the cable also makes it suitable for applications where it is exposed to long-term UV radiation, such as in outdoor installations or when installed in transparent enclosures.

Applications
This cable is specifically designed for fixed installation in industrial environments where reliable and interference-free data transmission is required. It is commonly used in automation systems that utilize PROFIBUS DP as the communication standard. The UV resistance extends its application to outdoor installations or areas with direct sunlight exposure. The maximum EMC shielding protects data transmission from electromagnetic interference generated by motors, transformers, or other electrical equipment.

Functions and Features in Detail
The bus cable has a construction of 1x2x0.64 mm², meaning two individual conductors, each with a cross-section of 0.64 mm², are housed together within a common protective sheath. This design ensures high mechanical stability and uniform shielding. The violet color serves as a visual identifier, simplifying cable management and identification. The PVC insulation provides good protection against mechanical stress and chemical influences. The UV resistance ensures that the cable does not degrade or lose performance even under prolonged exposure to sunlight.

Technology Explained Simply
The nominal characteristic impedance of 150 Ohm is a critical parameter for signal integrity in bus systems. It ensures that electrical signals are transmitted without reflections or distortions, which is essential for error-free communication between devices in the network. The Fast Connect (FC) technology allows for quick and secure connections with specialized connectors designed for PROFIBUS systems. The EMC shielding protects the cable from external electromagnetic interference that could disrupt data transmission. The PVC insulation offers good protection against mechanical damage and chemical influences, while the UV resistance ensures long-term stability in outdoor environments.

Compatibility and Accessories
The cable is designed for use in PROFIBUS DP networks and is compatible with corresponding connectors and bus systems. The Fast Connect (FC) technology requires specific connectors designed for this cable type. The UV resistance allows for use in environments where the cable is exposed to UV radiation, such as when installed in transparent enclosures or outdoors. The maximum EMC shielding makes the cable particularly suitable for applications in electromagnetically noisy environments, such as in manufacturing industries or machine control.

Installation and Mounting
The bus cable is intended for fixed installation and should be installed in accordance with electrical installation regulations. The violet color facilitates identification within cable harnesses. The PVC insulation provides good protection against mechanical stress, and installation should be carried out using appropriate tools and in compliance with regulations. The Fast Connect (FC) technology requires specific connectors designed for this cable type. The UV resistance permits outdoor installation, provided mechanical stress and environmental conditions are taken into account.
