PoE+ PSE Single Port Magnetic Jack

Molex Incorporated has developed the first single port PoE+ Power Source Equipment (PSE), single port magnetic jack in accordance to the IEEE802.3at standard. Based on the RJ45 jack and backward-compatible with the previous PoE IEEE802.3af standard, the PoE+ PSE single port magnetic jack, series 85759, is a complete, plug-and-play module that provides engineers with a simplified design process and easy migration path from using standard power supplies to fully integrated PoE+ capability.

The PSE-ICM offers the simplest solution for the design of a single port PSE. Eliminating complex design and testing provides OEMs with a faster time-to-market, reduced investment and lower direct and associated purchasing and production costs.

The footprint of the Molex PoE+ PSE single port magnetic jack is designed to optimize the separation distance of the signal and LED pins from the PoE circuitry, significantly reducing the complexity of PCB routing. The module has an external reset feature and capability to set maximum PoE class requirements (maximum power delivery allowed). Multiple LED configurations and colors are available, including single and bi-color.

Power over Ethernet (PoE) is a technology that defines the transmission of both data and power to networked devices over a standard Ethernet cable, eliminating the need for separate power supplies. PoE+ is the new IEEE802.3at standard. It provides the opportunity to increase port-power output to 30 watts, when set to Class 4. It supersedes the 15 watt (Class 0 to 3) IEEE802.3af standard, which was released 2004.

Additionally, Molex offers the 85789 series gigabit PoE+ enabled magnetic jack. PoE or PoE+ power can be sent or received through the connector with the PoE circuitry situated on the customer board. For non-PoE gigabit applications the 85793 series is available.
