Product details
Optimized for railway signaling systems, EDAC Inc.'s 638-078-232-043 D-Sub Connectors meets EN 50155 standards while withstanding 15G shock and 5G vibration. The robust design maintains signal integrity in electromagnetic environments up to 100V/m RF interference.The D-Sub, High Density configuration features double-locking mechanisms that prevent accidental disconnection in moving vehicles.Receptacle, Female Sockets contacts employ self-cleaning wiping action that maintains <20m resistance in dusty environments.The 78 layout includes segregated high-voltage and signal contacts with 8mm creepage distance.Precision-machined 4 contact arrays maintain alignment within 0.2mm during 50G shock events.Free Hanging (In-Line) variant incorporates vibration-resistant hardware that maintains torque retention after 10 million stress cycles.The 5 (DD, D) High Density design provides 80dB shielding effectiveness from 10kHz to 6GHz per EN 50121-4.Signal implementation uses nickel-cobalt alloys that maintain spring properties at -40 C to +125 C operating range.The Mating Side, Female Screwlock (4-40) system enables IP69K-rated sealing that withstands high-pressure washdown procedures.Our Solder Cup process creates crimp connections that survive 1000 thermal shock cycles from -40 C to +125 C.Steel, Nickel Plated demonstrates >500-hour resistance to railway lubricants and cleaning agents.The Gold surface treatment maintains <15m resistance after 1000 hours salt spray exposure.Precision-controlled Flash ensures proper wear resistance during 25,000 mating cycles.All materials exceed UL94 V-0 requirements per EN 45545-2 for railway applications.The 3A per Contact design incorporates parallel contact paths that maintain continuity during vibration.Shielded include integrated transient suppressors that protect against 1kV/500A surge pulses.
