Specification

SEODescription

The Siemens 6XV1843-2R FC is a shielded PROFIBUS DP Bus Cable engineered for high-speed industrial communication. Designed for PROFIBUS DP networks, it supports data rates up to 12 Mbps with a 150-ohm impedance, ensuring reliable signal integrity in noisy environments. This 6XV1843-2R PROFIBUS Cable features a robust double-layered shield (foil and braid) and twisted-pair copper conductors, operating within a voltage range of 30V to 200V and a temperature range of -30°C to +70°C. It directly connects up to 32 devices per segment, compatible with PROFIBUS DP/PA interfaces, and is widely used in automation, manufacturing, and process control industries. Its durable PVC sheath resists mechanical stress and chemicals, though its rigidity may complicate installation in tight spaces. Ideal for medium-distance networks, this cable ensures stable communication but requires proper grounding to minimize EMI risks.
