Hirose has developed a 2mm pitch, multi-functional connector system that provides wire-to-board, board-to-board joint and short circuit sockets in a single connector design. Designated the DF59 Series, the connector is intended for the LED market, as well as for many applications that require a small connector, such as battery connections, small DC motor drives and power supplies.
The DF59 has Hirose's unique "swing lock," which utilizes positive and friction locks, giving wire-to-board type connections cable pull force resistance. The cable end of the plug is mated at a slight angle to engage more fully with the receptacle and the other end of the plug is pushed down to complete mating with an audible tactile click. The connector also provides stress-free contact for 0.5mm floating function in XYZ directions for greater flexibility during the installation process.
Low mated height of 2.5mm and overall size of 8 x 9 mm
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
