Lisle, Ill. − Molex Inc. has launched its next-generation Power-over-Ethernet (PoE) plus magnetic PDJack connectors that simplify implementation and support PoE standards in networking devices. The single-port controller integrates power device controller circuitry and PoE functionality in a single solution for a space savings of up to 75 percent on a PCB compared to discrete solutions, said 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," said Diarmuid Cullinan, integrated products division manager, Molex, in a statement. "The PDJack connector with integrated power device controller circuitry plus Ethernet connectivity simplifies installation and the PoE plus infrastructure of networking devices."
Molex touts the device as 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 magnetic jack supports functions of all PoE PSE types as required for IEEE802.3at compliance, interoperability, thermal management and EMI standards. PoE Plus requires Category 5 cable or higher per the IEEE standard.
The PDJack is a fully-shielded connector with integrated electrostatic discharge (ESD) protection, and 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 supplies up to 25.5 W power at 37 V to 57 V. 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, said Molex.
Molex partnered with Microsemi and used its PD controller PD70200 in the PDJack connector. The PD controller 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.
