Connector Series Meets Category 7a Specs

The ARJ45 series of high-speed plugs and jacks is engineered to meet the proposed Category 7a performance parameters of up to 1000 MHz, far exceeding the IEC's current Category 7 standards. Initially consisting of a cable-mounted plug and single-port pc-board-mounted jack, the series is based on the industry-standard RJ45 interface and provides enhanced mechanical properties to accommodate the higher transmission speeds (see the figure). Stewart Connector collaborated with Nexans to ensure that the ARJ45 devices are interoperable and intermateable with Nexans' GG45 connector system.

The ARJ45 plug and jack are well-suited for Class Fa premise wiring systems, 10-Gigabit Ethernet, and higher-speed data-transmission systems. They may also be used as a low-cost connector replacement in closed-loop InfiniBand, Fibre Channel, EyeMAX, Serial Attached SCSI (SAS), PCI Express, and microTCA applications. The devices are made of UL94-VO plastics and use gold-plated (50-microinch) contacts to ensure high-cycle life. Operating temperature range is -40°C to 85°C. They're rated for 750 matching cycles. Voltage range is 150 V ac, and current rating is 1.5 A at 25°C.

Prices for the ARJ45 jacks start at $3.50 each in quantities of 1000. Samples are available now, and production quantities will ship early in the first quarter of 2007.
