449423-3

The 449423-3 from TE Connectivity Aerospace, Defense and Marine sets new standards in Backplane Connectors - ARINC Inserts for railway signaling systems. Developed to withstand extreme environmental conditions, these connectors feature corrosion-resistant alloys and IP67-rated housings. The 449423-3 maintains stable electrical characteristics across -40 C to +105 C operating ranges, critical for trackside equipment reliability.Offered in Pin Assembly variants, this product line accommodates diverse rail signaling architectures. The polarized versions prevent mis-mating in low-visibility conditions common in underground transit systems.Featuring 100 arrangements, these connectors optimize space utilization in control cabinets. The 3-row design achieves 30% higher contact density than standard rail connectors while maintaining 5A current rating per contact.
