Product details
Amphenol Aerospace Operations's D38999/26SH55BN revolutionizes Circular Connectors - Housings technology for high-speed rail applications. Engineered to withstand extreme vibration and weather conditions, this connector ensures reliable performance in train control systems and onboard electronics where safety is paramount.The Plug Housing configuration survives 10G vibration levels in locomotive applications. Field testing demonstrates 99.999% reliability over 1 million mating cycles.Optimized for For Female Sockets implementations, the contact system resists fretting corrosion in high-vibration environments. The multi-point contacts maintain <5m resistance under 5-200Hz vibration.With 55 contact arrangements, the design supports distributed power systems. The isolated high-current contacts prevent arc tracking in 1500V DC applications.Compatible with 23-55 inserts, allowing flexible power/signal configurations. The floating insert accommodates panel warpage up to 3mm.Conforming to H standards, the connector interfaces with industry-standard railway accessories. The robust design withstands 1000N mating force without deformation.Crimp termination ensures reliable connections in thermally dynamic environments. The spring-loaded contacts compensate for 10mm of thermal expansion.Designed for 20 contacts, the current density remains below 250A/cm at full load. The optimized contact geometry reduces insertion force by 30%.The Free Hanging (In-Line) installation withstands 50G shock loads during rail impacts. The vibration-resistant design maintains contact integrity under 5-500Hz random vibration.Threaded locking mechanism provides positive engagement in all weather conditions. The self-cleaning threads operate flawlessly from -40 C to +85 C.Featuring N (Normal) keying, the connector prevents mismating in identical-looking cable runs. The color-coded system reduces installation errors in maintenance depots.The Stainless Steel construction provides excellent impact resistance in derailment scenarios. The material meets EN 45545-2 fire safety standards for railway applications.Nickel coating maintains <10 contact resistance after salt spray exposure. The surface treatment withstands abrasive particles in tunnel environments.The Silver identification system complies with EN 50155 railway standards. High-visibility pigments remain detectable in all lighting conditions.The Coupling Nut, Firewall Usage, Self Locking include integrated surge protection up to 10kA impulse current. The gas-discharge tube design protects sensitive electronics from lightning strikes.Shielded effectiveness meets EN 50121-3-2 railway EMC standards. The continuous braid design provides 80dB attenuation at 100MHz.
