The HCI® connector system anticipates the continued trend toward increased system power demands that is driving the need for increased power density. The HCI® connector system is designed to address requirements that extend beyond the capability of FCI's proven PwrBlade® connector system, the industry standard for DC power supply interfaces and power distribution.

The HCI® connector system likewise provides capability for both power and signal contacts in a single connector to enable power distribution and power control. Integrated HCI® power connector solutions, enabling DC power, AC power, and signal contacts in a single molded housing, also provide incredible flexibility to address requirements for custom configurations.

The HCI® connectors employ stamped and formed power contacts, initially pioneered by FCI with its PwrBlade system, as an innovative and cost effective alternative to expensive screw-machined contacts for high-current applications.

The touch-proof HCI® housing is designed to optimize airflow. The housing permits airflow through the connector by providing vents above the signal field as well as vents above the power contacts that permit airflow away from the mated interfaces and along the entire length of the contacts.

Available HCI® options support standard coplanar (right-angle header to right-angle receptacle) and backplane (right-angle header to vertical receptacle) form factors.

Features & Benefits

• Integrated design with power, signal contacts and guides in a single connector housing
• Vented housings dramatically improve airflow and thermal performance while maintaining touch-proof design
• Lowest product height in the industry for a cost-effective, stamped-andformed power connector with comparable current density
• Single short detect contact is available as an option to 'power-on' the application
• Flexible, expandable product platform permits variation in the number and placement of signal, DC and AC power contacts within the molded housing
• Integrated, industry-standard molded-in guidance system compensates for four degrees of radial misalignment for predictable cost effective blind mating
• Hard Metric mating compatibility (12.5mm from card-edge to board in the backplane)
• Options for either perpendicular or coplanar board-to-board configurations
• Press-fit termination of vertical backplane receptacle and though-hole solder termination of right-angle headers and receptacles are available to meet application requirements
