Product details
Hirose Electric Co Ltd's DF81DJ-40P-0.4SD(51) sets new standards in Rectangular Connectors - Free Hanging, Panel Mount for railway and transportation systems. This rugged interconnect solution meets EN 50155 and IEC 61373 specifications, delivering reliable performance in rolling stock applications despite extreme vibration, shock, and environmental conditions.The Plug configuration features a double-locking system that withstands 50G shock pulses. The vibration-resistant design maintains electrical continuity through 10Hz to 2kHz random vibration profiles.Utilizing Outer Shroud Contact technology, these contacts maintain less than 5m resistance variation under 15G vibration. The hyperbolic contact geometry compensates for terminal movement while maintaining constant normal force.Available in 40 configurations, the connector supports both power distribution and train communication networks. The segregated contact groups prevent interference between high-voltage and sensitive signal circuits.The 0.016" (0.40mm) spacing provides sufficient clearance for 3000V AC isolation requirements. The molded barriers between contacts prevent tracking in humid environments per EN 50124-1.The 1 row arrangement positions power contacts for optimal heat dissipation. The thermal management design reduces hot-spot temperatures by 20% compared to conventional layouts.The Free Hanging (In-Line) version includes integrated cable clamps meeting EN 50264 standards. The corrosion-resistant stainless steel hardware withstands railway cleaning chemicals.Featuring Solder technology, the system accommodates both fine-strand and rigid conductors. The spring-loaded cage clamp maintains constant pressure despite vibration-induced relaxation.Compatible with Discrete or Ribbon Cable railway cables, the contacts resist micro-movement induced fretting corrosion. The tin-plated termination surfaces maintain stable contact resistance in humid environments.Supporting 34-36 AWG, 36-46 AWG conductors, the power contacts carry 150% of rated current for 5 minutes without derating. The parallel contact springs compensate for thermal expansion effects.With 2.00µin (0.051µm) plating, the contacts maintain less than 10m resistance after EN 61373 vibration testing. The nickel barrier layer prevents base metal corrosion.The Black housing incorporates retro-reflective markings for improved visibility in low-light conditions. The high-temperature resistant material maintains mechanical properties from -40 C to +125 C.
