Product details
Optimized for railway signaling systems, Kycon, Inc.'s K42X-B25P/S-A4N 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 - Stacked configuration features double-locking mechanisms that prevent accidental disconnection in moving vehicles.Plug, Male Pins; Receptacle, Female Sockets contacts employ self-cleaning wiping action that maintains <20m resistance in dusty environments.The 25, 25 layout includes segregated high-voltage and signal contacts with 8mm creepage distance.Precision-machined 2, 2 contact arrays maintain alignment within 0.2mm during 50G shock events.Through Hole, Right Angle variant incorporates vibration-resistant hardware that maintains torque retention after 10 million stress cycles.The 3 (DB, B); 3 (DB, B) 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 Housing/Shell (4-40) system enables IP69K-rated sealing that withstands high-pressure washdown procedures.Our Solder 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 1.2A design incorporates parallel contact paths that maintain continuity during vibration.0.318" (8.08mm) dimensional control ensures proper clearance for 5mm thick cable insulation.Board Lock, Grounding Indents, Mounting Brackets include integrated transient suppressors that protect against 1kV/500A surge pulses.
