ARJ45® Connector Systems

The ARJ45® connector system is Stewart Connector’s new family of products for Category 7 and Category 7a premise wiring systems deployed in 10Gigabit Ethernet and higher speed data transmission environments. This connector family consists of a cable-mounted plug and a single-port, PCB-mounted jack designed to meet Category 7a performance standards up to 1000 MHz as defined by the IEC60603-7-71. Additionally, the ARJ45 connector system can be used as a high speed replacement for closed loop applications currently using less economical connector types.

Stewart Connector’s ARJ45 connector systems provide a competitive advantage in that they are built on the proven reliability of standard RJ45 interface mechanics which have been enhanced to support increased Category 7a data speeds. In addition, the ARJ45 connectors are interface-compatible with the Nexans’ GG45 connector system.
