FCI Offers BarGuide Power Connectors for High-Power Distribution

FCI Electronics has released a new lineup of BarGuide power connectors, designed for high power distribution in high-density packaging. These connectors provide high amperage connections between busbars and circuit boards as well.

FCI’s new BarGuide connectors provide a current carrying capability from 60 to 250 amps, based on the specified pin sizes; these connectors are available in five different pin-size versions. These BarGuide power connectors are available with press fit printed circuit board (PCB) tails for mounting on both circuit boards and busbars. A busbar is a metallic bar or strip that is used to conduct a substantial current of electricity, but does not function as a structural member.

Typical applications for FCI’s new BarGuide power connectors include AC/DC pluggable power supplies in telecom and datacom, networking equipment and switches, as well as use in servers for data storage. The connectors come in both vertical and right angle designs, which provide either parallel or perpendicular interconnections.

FCI’s BarGuide connectors provide a high-current, low power-loss interconnection with a quick connect and disconnect function for space-constrained power distribution applications, whether board-to-board, board-to-busbar, or busbar-to-busbar. The connectors use a high-performance spring that with a particularly large contact area. This helps prevent voltage loss, and keeps heat and insertion/extraction forces to a minimum.

The new BarGuide connectors feature low-resistance and low-voltage drop, a wide current carrying range, a wide operating temperature of -40 °C to 125 °C and convenience in mounting on circuit boards or busbars. FCI’s AGT plating technology provides maximum conductivity and long-term reliability.

In addition, FCI’s new BarGuide connectors are compliant with Restriction of Hazardous Substances (RoHS) directives.

The many other features and benefits of FCI’s new BarGuide connectors include the following:

  • High-performance spring and silver plating
  • Diverse pin sizes, including 3mm, 3.6mm, 5.7mm, 6mm and 8mm diameters
  • Housing with high temperature and halogen-free resin
  • Compliant press-fit tails

FCI Electronics designs and manufactures a wide array of high-tech connector solutions for various market applications, including data storage, motorized vehicles, consumer electronics, telecommunications, as well as industrial and medical instrumentation. The company’s products include: cable assemblies, board/wire to board connectors, flex connectors, optical interconnect, backplane, terminal blocks, power solutions, and input/output connectors.
