Product details
Molex's 0857911020 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 1 redundant ports, this configuration enables fault-tolerant signaling architectures required by CENELEC SIL-4 standards.The 1 row arrangement provides adequate creepage distance (>12mm) for 3000VAC isolation in trackside applications.Certified for 10/100/1000 Base-T, AutoMDIX, Power over Ethernet+ (PoE+) railway implementations, this connector meets EN 45545-2 fire safety requirements for rolling stock.The 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 0.546" (13.87mm) profile allows proper clearance for arc flash protection in 3000VAC signaling systems.Does Not Contain LED 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 Lock, this connector provides integrated surge protection up to 10kV for lightning-prone environments.The Up latching mechanism meets EN 50274 requirements for finger-safe connections in railway applications.Phosphor Bronze contacts exhibit excellent resistance to sulfur dioxide and other rail corridor pollutants.Rated for 0°C ~ 70°C operation, this component performs reliably from arctic winters to desert rail conditions.
