Product details
Souriau-Sunbank by Eaton's 8LT721F39SN-LC 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 Receptacle 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 39 contact arrangements, the design supports distributed power systems. The isolated high-current contacts prevent arc tracking in 1500V DC applications.Compatible with 21-39 inserts, allowing flexible power/signal configurations. The floating insert accommodates panel warpage up to 3mm.Crimp termination ensures reliable connections in thermally dynamic environments. The spring-loaded contacts compensate for 10mm of thermal expansion.Designed for 16 (2), 20 (37) contacts, the current density remains below 250A/cm at full load. The optimized contact geometry reduces insertion force by 30%.The Panel Mount installation withstands 50G shock loads during rail impacts. The vibration-resistant design maintains contact integrity under 5-500Hz random vibration.The Bulkhead - Front Side Nut design allows one-handed installation while wearing gloves. The captive hardware prevents dropped components during overhead line work.Bayonet Lock 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 Aluminum Alloy 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.Exceeding Environment Resistant requirements, the design withstands high-pressure washdowns in train cleaning systems. The triple-seal interface prevents moisture ingress during thermal cycling.Unshielded effectiveness meets EN 50121-3-2 railway EMC standards. The continuous braid design provides 80dB attenuation at 100MHz.
