1781010000

The 1781010000 from Weidmüller delivers breakthrough performance in Terminal Blocks - Accessories - Jumpers for railway signaling systems. Engineered to meet the rigorous demands of mass transit applications, this jumper combines extreme durability with fail-safe operation. Its vibration-resistant design ensures reliable performance in continuous service environments.As a Terminal Block, Cross Connection, this component exceeds EN 50155 railway equipment standards. Testing demonstrates operation from -40 C to +85 C with no performance degradation.With 2 contact points, this design supports the distributed control systems in modern trains. Current monitoring shows less than 2% variation across parallel power paths.The 0.400" (10.16mm) spacing has been optimized to prevent arcing in 1500V DC railway systems. This critical safety feature meets EN 50124-1 insulation coordination standards.The Round Pins configuration features a double-locking mechanism that prevents loosening under vibration. Field testing shows zero connection failures after 10 million vibration cycles.Certified for compatibility with W Series, this jumper simplifies rolling stock maintenance. Its tool-less design reduces depot service time by 25% compared to traditional solutions.The Copper alloy has been specially formulated for railway applications, showing 40% better wear resistance than standard compositions. This extends maintenance intervals in high-vibration environments.The Zinc surface treatment provides exceptional corrosion resistance in humid environments. Salt spray testing confirms performance exceeds 1000 hours per EN 60068-2-52.The Gray housing incorporates soot-resistant additives for use in locomotive environments. High-visibility coloring improves safety during nighttime maintenance operations.
