Product details
Bel Fuse Inc.'s C855-2B4R-54 sets new benchmarks in Modular Connectors - Jacks With Magnetics technology for railway signaling systems. This vibration-resistant connector solution combines fail-safe design with advanced EMI protection, making it critical for train control and trackside equipment. The robust construction ensures reliable operation in extreme weather conditions.The RJ45 interface features positive-locking mechanisms that withstand 15G vibration per EN 50155 railway standards.With 8 redundant ports, this configuration enables fault-tolerant signaling architectures required by CENELEC SIL-4 standards.The 2 row arrangement provides adequate creepage distance (>12mm) for 3000VAC isolation in trackside applications.Certified for 10/100/1000 Base-T, AutoMDIX railway implementations, this connector meets EN 45545-2 fire safety requirements for rolling stock.The Board Edge, Through Hole installation method withstands 50G shock loads specified by IEC 61373 Category 1 testing.90° Angle (Right) PCB alignment facilitates maintenance access in tight signal boxes while preventing cable strain.Employing Solder technology, the contact system maintains <2m resistance after 1000 thermal cycles (-40 C to +85 C).The 0.829" (21.06mm) profile allows proper clearance for arc flash protection in 3000VAC signaling systems.Orange, Green - Orange, Green indicators feature sunlight-readable brightness (>8000cd/m ) for outdoor trackside applications.The 8-core design supports simultaneous power and data transmission for ERTMS/ETCS systems.Shielded, EMI Finger effectiveness exceeds 70dB at 1GHz, critical for preventing interference with GSM-R communications.Incorporating Board Guide, this connector provides integrated surge protection up to 10kV for lightning-prone environments.The Up and Down latching mechanism meets EN 50274 requirements for finger-safe connections in railway applications.Copper Alloy contacts exhibit excellent resistance to sulfur dioxide and other rail corridor pollutants.The Gold plating maintains stable contact resistance after 1000 hours in mixed flowing gas testing.Rated for 0°C ~ 70°C operation, this component performs reliably from arctic winters to desert rail conditions.
