Hirose launches bus-bar plug-in connector with floating alignment

Nov. 30, 2016

Downers Grove, IL. Hirose has introduced a floating bus-bar connector with plug-in mating to simplify assembly, maintenance, and expansion. Supporting up to 300 A, the PS4 Series connector has a floating contact alignment that can absorb mounting misalignment of up to 2 mm in the XY direction to ease installation in data centers, power distribution units, storage battery systems, uninterrupted power supplies, and more.

Plug-in mating not only reduces assembly and maintenance time, but also increases safety and reliability. Plug-in mating eliminates the need for the installer to touch the conductor, while ensuring a rugged connection regardless of the installer’s skillset.

With a compact design applicable to 1U size, the high current PS4 Series bus bar is available in 150-A and 300-A versions. The 150-A PS4 is designed for use with a bus-bar thickness of 3.175 mm (0.125 inches), while the 300-A version supports a bus-bar thickness of 6.35 mm (0.25 inches). The high current rating is supported by reducing the contact resistance via a larger contact area and multiple contact points. This design also decreases heat generation caused by current flow, which increases performance and operational life.

The PS4 Series’ patent-pending mating design allows for connector float in the XY direction, then locks in place after full engagement with the bus bar.

“The compact PS4 Series connector has a unique design that makes installation easy by allowing it to float to the most appropriate mating position where it aligns with the bus bar,” said Rick van Weezel, vice president of sales and marketing for Hirose Electric USA. “The plug-in mating connector offers significant advantages over competing products including reduced assembly, reduced maintenance time and lower costs, enhanced reliability, and increased worker safety.”

The PS4 Series connector has a rated voltage of 600 V AC/DC and an operating temperature of -40 to +105°C.
