Molex recently launched its next-generation PoE plus magnetic PDJack connectors. The single-port controller integrates power device controller circuitry and PoE functionality in a jack. The connector's design conserves up to 75 percent of space savings on a PCB compared to discrete solutions, reckons the company.
“The PDJack connector with integrated power device controller circuitry plus Ethernet connectivity simplifies installation and the PoE plus infrastructure of networking devices,” states Diarmuid Cullinan, integrated products division manager at Molex. “Based on the RJ45 connector, the fully compliant PDJack connector eliminates complex design and testing for lower direct costs and faster time-to-market.”
The company claims the new product is the industry’s first integrated power device jack, combining PoE plus power device controller and bridge rectifiers with gigabit magnetics in a drop-in single port connector solution. The new PDJack connector supports functions of all PoE PSE type as required for IEEE802.3at compliance, interoperability, thermal management and EMI standards.
In developing the PDJack connector, Molex partnered with Microsemi for its PD controller PD70200, which meets all power device standards including detection, classification, integrated isolation switch with inrush current limiter and over-current protection, and two events classifications for PoE plus power.

A fully-shielded connector with integrated electro-static discharge protection, the robust PDJack connector design is suitable for a wide operating range and passive airflow environments. Available in Class 0, 1, 2, 3 and 4 for optimal power design, the PDJack connector supply up to 25.5W power at 37V to 57V. Two pins output power and standard signal pins provide Ethernet connectivity, with additional pins allowing power-up of external DC to DC converter.
The PDJack manages all the communications with the switch/router PoE controllers to negotiate power requirements and manage safe power-up and power down of IP devices, wireless access points, control panels, vision systems and POS units. PoE Plus according to the IEEE standard requires Cat 5 cable or higher. For more information on the PDJack connector, visit: www.molex.com/product/poe.html.
