Mod jack combines RJ45 interface with Cat 7a performance

Glen Rock, Pa. — Bel Stewart Connector, a division of Bel Fuse Inc. offers the ARJ45 Series of high-speed Category 7a modular jacks with integrated magnetics to support 10GBase-T performance parameters as defined by IEEE 802.3an-2006.

Bel Stewart has extended its existing magnetic technology into the Category 7a ARJ45 jack, the company’s newest twisted-pair connector interface. The ARJ45 jack provides a connector solution for the to-be-defined, next-generation IEEE twisted-pair Ethernet standards as the high frequency requirement of these future standards will likely exceed the limitations of existing RJ45 connectors, said Bel Stewart.

The mechanical interface of the ARJ45 connector series meets the IEC 61076-3-110 standard, and the overall construction facilitates integration with the magnetics required for twisted-pair Ethernet data transmission. The connector’s interface also provides the familiarity of an RJ45-style device in its use and port density, along with the performance benefits of a Category 7a connector system.

Bel Stewart’s standard ARJ45 connector product line includes passive 90-degree PCB-mounted jacks along with plugs and cable assemblies, offering integrated strain relief boots and anti-snag features for plug tab protection. ARJ45 connectors are provided standard with gold-plated (50-microinch) contacts to ensure high-cycle life and are manufactured of UL94-VO plastics.

The voltage range is 150 Vac, and current rating is 1.5 A at 25 degrees C. The operating temperature range is -40 degrees to +85 degrees C and the durability rating is 750 matching cycles.
