Product details
Hirose Electric Co Ltd's DF4-3PA-2R28 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 Individual Wires configuration features double-locking mechanisms that prevent accidental disconnection in high-vibration railway applications, from locomotive controls to passenger information systems.Available in 3 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 0.079" (2.00mm) alignment ensures reliable connections in train communication networks where signal integrity affects critical systems like automatic train control.The 0.079" (2.00mm) board interface accommodates vibration-resistant mounting techniques required in railway vehicle control electronics.The 1-row design incorporates robust strain relief that maintains connection integrity despite constant vibration in subway cars and light rail vehicles.Through Hole, Right Angle 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 28 AWG, Stranded conductors, the connector handles both signal-level communications and high-current applications like door controls and HVAC systems in passenger coaches.The Closed End include integrated shielding that meets EN 50121-3-2 EMI requirements for railway applications, preventing interference with signaling systems and onboard electronics.Tin plating resists micro-arcing in DC power distribution systems while maintaining reliable connections in humid environments like subway tunnels.The Black housing meets railway industry color-coding standards while providing UV resistance for exterior applications like train coupler connections and rooftop equipment.
