111035-4

TE Connectivity Aerospace, Defense and Marine's 111035-4 sets new standards in Rectangular Connectors - Board In, Direct Wire to Board reliability for railway and mass transit applications. Designed to meet EN 50155 and other rail industry standards, this connector series withstands the unique challenges of rolling stock environments.The Ribbon Cable configuration features double-locking mechanisms that prevent accidental disconnection in high-vibration railway applications, from locomotive controls to passenger information systems.Available in 24 variants, this connector family supports the full range of railway electrical systems, from low-voltage sensor interfaces to 1,500V traction power monitoring circuits.Precision 0.050" (1.27mm) alignment ensures reliable connections in train communication networks where signal integrity affects critical systems like automatic train control.The 0.200" (5.08mm) board interface accommodates vibration-resistant mounting techniques required in railway vehicle control electronics.The 4-row design incorporates robust strain relief that maintains connection integrity despite constant vibration in subway cars and light rail vehicles.0.100" (2.54mm) separation prevents flashover in high-voltage applications like overhead line monitoring systems and traction power distribution.Through Hole mounting ensures secure attachment to vehicle frames while allowing for thermal expansion in exterior-mounted equipment exposed to temperature extremes.Employing IDC technology, the connector achieves IP67 protection against dust and moisture ingress, critical for undercarriage equipment and roof-mounted antenna systems.Supporting 26-28 AWG, Stranded or Solid conductors, the connector handles both signal-level communications and high-current applications like door controls and HVAC systems in passenger coaches.The Feed Through include integrated shielding that meets EN 50121-3-2 EMI requirements for railway applications, preventing interference with signaling systems and onboard electronics.Tin-Lead plating resists micro-arcing in DC power distribution systems while maintaining reliable connections in humid environments like subway tunnels.With 100.0µin (2.54µm) plating, the contacts withstand the mechanical stress of thousands of mating cycles in passenger door systems and other frequently accessed connections.The Black housing meets railway industry color-coding standards while providing UV resistance for exterior applications like train coupler connections and rooftop equipment.
