Tyco Electronics released a new interconnect that enables power-over-Ethernet (PoE) functionality to be embedded within the connector, reducing the cost, footprint and design-cycle time associated with integrating PoE into Ethernet switches.

The Mag45 PoE RJ-45 connector provides the networking industry with a product that scales from 10/100 to 10/100/1000 and includes integrated magnetics and integrated power management silicon.

The new 802.3af specification defines how power will be available over the existing Ethernet cabling infrastructure, Tyco explained. Network switch manufactures will have the ability to provide power to the LAN to support powered devices including IP telephones, remote security cameras and wireless access points. In addition, the new specification will eliminate the need for a co-located AC power source at the powered device location and make it more convenient to access 15W of DC power from a standard RJ45 wall outlet.

The new Mag45 connector integrates power management silicon manufactured by PowerDsine into a standard 12-port RJ-45 connector. The connector also fits into the same panel dimensions as legacy 2X6 RJ-45 products and supports a total of 48 ports in a standard 19 inch rack.

According to the company, a key design feature incorporated into the new connector is a common footprint that provides customers the flexibility to design their PCBs for non PoE, PoE-enabled and PoE-integrated applications. Customers save PCB layout and design time, real estate, and layer count while maintaining a very easy migration path to networking products for 10/100 and gigabit 802.3af-compliant PoE switches and routers, the press release said.

The Mag45 connector will initially be available in a press-fit style. Pricing for the connector line with LEDs ranges between $2.50 and $6 per port at 1,000-piece quantity, and pricing for other configurations and options are available upon customer request.
