4-644578-3

TE Connectivity AMP Connectors's 4-644578-3 sets new standards in Rectangular Connectors - Free Hanging, Panel Mount technology, optimized for industrial automation systems requiring robust connectivity. This advanced interconnect solution combines military-grade durability with precision signal transmission capabilities, delivering unmatched performance in factory automation and process control applications.The Receptacle configuration features a unique anti-vibration design that maintains secure connections in high-impact environments. The overmolded strain relief prevents cable fatigue in continuous flex applications.Utilizing Female Socket technology, these contacts demonstrate 30% lower contact resistance than industry benchmarks. The hyperbolic contact geometry ensures consistent pressure across the mating surface.Scalable to 13 contacts, this modular system supports daisy-chaining for distributed control networks. The numbered position indicators facilitate error-proof field servicing.The 0.100" (2.54mm) centerline spacing accommodates high-voltage isolation requirements while maintaining compact dimensions. This spacing effectively prevents arc-over in 600VAC industrial applications.The 1 row matrix provides optimal balance between current capacity and connector footprint. The interleaved power and signal contacts enable integrated power distribution.Free Hanging (In-Line), Right Angle variants include tool-less installation features for reduced maintenance downtime. The patented latch design allows single-handed operation while wearing gloves.The Locking Ramp system exceeds IEC 61076-2-101 mechanical endurance requirements. The dual-stage locking mechanism provides both preliminary and final securement.The IDC system incorporates automatic wire stop technology for precise termination depth control. This feature eliminates guesswork during field installations.Engineered for Discrete or Ribbon Cable cabling, the contact slots are laser-trimmed to prevent insulation nicking. The precision-formed crimp barrels ensure uniform compression across all wire strands.Supporting 22 AWG conductors, the contacts maintain proper spring tension throughout the wire's temperature expansion range. The dual-crimp design secures both conductor and insulation.The Feed Through include integrated transient voltage suppression for surge protection. These built-in safeguards protect sensitive equipment from electrostatic discharge events.Tin surface treatment provides excellent wear characteristics for frequent mating cycles. The selective plating process concentrates precious metals at critical contact points.With 80.0µin (2.03µm) plating, the contacts achieve Class 3 performance per MIL-STD-202. The controlled diffusion layer prevents pore corrosion in humid conditions.The Black housing material includes embedded FR additives meeting UL94 V-0 flammability ratings. Color-coded versions are available for quick visual identification in control panels.
