Mechanical Design and Durability
The 6ES5734-0BD20 incorporates overmolded strain relief boots on both connector ends. This design prevents conductor fatigue from repeated bending cycles. Gold-plated contacts ensure reliable signal integrity and corrosion resistance. Dual-layer shielding effectively rejects electromagnetic interference from surrounding equipment. The flexible PVC jacket withstands oils and chemicals commonly found in industrial environments.
Application and Compatibility
This programming cable connects S5 CPUs to programming devices and PCs. The 3-meter length provides sufficient reach between cabinet and workstation. Users can rely on this cable for consistent communication at 19.2 Kbps. The cable works with both STEP 5 and other S5 programming software environments. Its robust design suits frequent connection and disconnection cycles in maintenance operations.
