CONNECTION SYSTEMS
Delphi Harsh Environment Series (HES)
Connection Systems
The Delphi 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). Delphi'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.
Delphi HES Connection Systems are also compatible with
existing systems in the commercial and agricultural vehicle
markets.
Benefits
•
Terminals
o
o
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
o
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
o
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
o
Interchangeability with industry standard circular products
o
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
o
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
o
Virtually eliminates unseats with Delphi’s two stage
terminal retainer design
o
High vibration design passes 29 Grms vibration
specification
o
Chemical resistant header face seals with the use of
flourosilicone
o
Built-in probing window protect the female terminal
during the build process
o
Over-torque bolt design protects the header when too
much torque is applied
o
True pin position is one of the tightest in the industry at
0.225 mm, ensuring easy mounting to a circuit board
o
Interchangeability with industry standard products
Typical Applications

Agriculture
Commercial vehicle
Construction
Marine
Other harsh environment applications
HES Circular Connectors
The HES circular design is ideally suited for making
connections in a vehicle sheet metal firewall pass-through
locations. Because of the rugged connection system design,
they are well suited for engine compartments. HES headers
are an ideal choice for high density device I/Os that are
mounted directly to the engine.
