Aptiv HES Series Connection Systems

Harsh Environment Series connection systems

The Aptiv Harsh Environment Series (HES) Connection Systems include circular connectors, terminals, and a rectangular 50 and 60 way header. The 24 shell size industry standard connector includes six terminal configurations (47, 31, 29, 23, 21, and 19). Aptiv's circular connection systems are available with straight and right angle conduit wire dress covers on both receptacle and plug assemblies.
The HES Connection Systems provide higher current capability, improved sealing, higher terminal retention and a significant cost advantage compared to standard pin-and-sleeve systems. Aptiv HES Connection Systems are also compatible with existing systems in the commercial and agricultural vehicle markets.

Delphi Harsh Environment Series (HES) Connection Systems - Avnet Abacus


  • Terminals
    • High current performance is realized through the selection of high conductive materials
    • Robust design with a stainless steel sleeve that provides stability and protection to contact interface area
    • Overlapping wing design provides exceptional strain relief and larger outside diameter cable range capability
    • Crimp stability over the terminal life with the use of tin in the crimp area
    • Wide range of cable sizes accommodated with Delphi's crimp design
    • Interchangeability with industry standard terminal products
  • HES Circular Connectors
    • Sealing performance exceeds expectations with recessed 3-rib design that will maintain sealing properties even if a tight wire dress is applied, providing better sealing capability up to 30% compared to existing designs
    • Superior contact (terminal) retention performance virtually eliminates terminal unseats with a specialized finger design that results in better retention up to 40% when compared to existing designs
    • Interchangeability with industry standard circular products
    • Ergonomic design for ease of assembly and to maintain quality:
      • Arrows help simplify pre-engagement of locking collar for simplified mating
      • Visual lock engagement window
      • Color coded seals to distinguish between various cable diameters as well as terminal gender
      • Low torque engage
    • Robust construction through sonic welding the seal retainer construction and using wave spring design that ensures the connection system maintains face seal compression, even when subjected to the high vibration commercial vehicle SAE J-2030 standard
  • Header System
    • Virtually eliminates unseats with Delphi’s two stage terminal retainer design
    • High vibration design passes 29 Grms vibration
    • specification
    • Chemical resistant header face seals with the use of flourosilicone
    • Built-in probing window protect the female terminal during the build process
    • Over-torque bolt design protects the header when too much torque is applied
    • True pin position is one of the tightest in the industry at 0.225 mm, ensuring easy mounting to a circuit board
    • Interchangeability with industry standard products
  • Typical Applications
    • Agriculture
    • Commercial vehicle
    • Construction
    • Marine
    • Other harsh environment applications
