This FAQ reviews the architecture and performance features of the HDC. For a discussion of HDC-related standards, see the "Which Standards Apply to Heavy Duty and Industrial Connectors" FAQ. (Published Wednesday, October 11)
HDC construction includes high-performance materials such as metal or thermoplastic housings, durable plastics for plugins, and shock-proof and airtight terminals. They need to withstand high mechanical stress, including shock and vibration, and offer protection grades from IP65 to IP69k for dust and water resistance.
HDCS come in a variety of sizes and can be modular in construction, where various types of pins can be mixed and matched for specific applications, making these connectors highly versatile and adaptable. Guards and housings, terminal systems, and plug-ins are common components in many HDCS
The hood and housing must be impact-resistant and sturdy. They can be made of powder-coated metal, die-cast aluminum alloys with a polyester powder surface, or they can be left in their natural state for better electromagnetic compatibility (EMC) performance, self-flameout thermoplastics, or other robust materials. Some common features include:
IP65, IP67, IP68 and IP69k grades
Voltage and EMC resistant construction
Special hard anodized coatings with excellent corrosion properties provide up to 1,000 hours of salt spray resistance testing
In addition to supporting power, data, and signal terminals, terminal systems offer a high degree of flexibility, and they come in a variety of configurations, including:
Power contacts rated from 5 to 650 A can handle voltages up to 1,000 V
Vibration proof and pressure contact points with airtight ends
Screw termination
Spring clamp ends.
Plugins are also available in a variety of configurations, including a single housing with multiple contact types for modular configuration. Performance can include:
Certification to TUV, UL, IEC, DIN and other standards
Polarization for correct mating.
Some models can accommodate 288 or more contacts.
The flexibility of the HDC is further enhanced by the availability of various cable connectors, fittings, locking mechanisms, washers and other accessories, such as:
Cable protection and sealing accessories
Metal and plastic cable joints available in a variety of IP grades and geometries, such as right angles and right angles
Accessories for flexible conductors
Enlarger and shrinking machine
Single, double and screw locking mechanisms
Special locking nut

While flexibility is critical, HDC ultimately delivers high performance levels, starting with durability and long service life in harsh environments such as automation and transportation systems. They need to provide security and protection for people and systems. Safety considerations include safe operation in the presence of mechanical stress and vibration, electrical isolation, EMC performance and a high level of intrusion protection.
HDC provides high-density connectivity solutions that enable compact and flexible system designs. They speed up installation and maintenance because many signal, power, and data connections can be established in a single operation. The housing can be used for surface, partition or screw mounting, further increasing design flexibility. HDC can provide cable termination or cable to cable connection.
The HDC is a rectangular connector optimized to provide high-power connections and data and signal pins with high signal density in a single housing. They are environmentally friendly, support high-density solutions, and offer optional features and accessories.
