Molex: PoE Plus Integrated PDJack™

Molex 85791 PDjack

PDJack™ with integrated Power Device controller circuitry plus Ethernet connectivity simplifies PoE Plus implementation for any network device, reducing time-to-market, lowering costs and achieving considerable PCB space savings.

Based on the RJ45 connector, the magnetic PDJack™ is the first integrated PD (Power Device) Jack in the market to combine a PoE+ PD controller and bridge rectifiers with gigabit magnetics in one connector and provide a complete drop-in, single port solution.

Situated on the customer printed circuit board (PCB) the PDJack supplies 54 volt power of up to 25.5 watts. Two pins output power and standard signal pins provide Ethernet connectivity. Additional pins allow power-up of external DC to DC converter. The PDJack manages all the communications with the switch/router PoE controllers: negotiating power requirements and managing safe power-up and power down of PD devices such as IP phones, IP cameras, wireless access points, control panels, vision systems and point of sale (POS) units. PoE Plus according to the IEEE standard requires Cat5 cable or higher.
