Specification

SEODescription

The Siemens 6XV1870-3QH20 PROFIBUS Type A Cable is a high-performance shielded cable designed for robust industrial communication networks. This 6XV1870-3QH20 Shielded Cable features a twisted-pair configuration with aluminum foil and braided shielding, ensuring reliable data transmission at speeds up to 12 Mbps in PROFIBUS DP/PA applications. It supports direct connections for up to 32 nodes per segment and operates within a voltage range of 30 V DC, with a temperature tolerance of -30°C to +70°C, making it ideal for harsh environments in manufacturing, process automation, and machinery. The cable’s durable PVC jacket and EMI-resistant design enhance signal integrity over long distances. While its rugged construction ensures longevity, proper grounding of the shield is critical to avoid signal degradation. This cable is widely used in industries requiring stable, high-speed PROFIBUS communication.
