Ethernet transformer without PoE power supply

The network port RJ45 connector is randomly selected as a mechanical part that "can be plugged into a network cable". As a result, the radiation emission exceeds the standard, ESD kills it, the shielded network cable is even worse when plugged in, and the board is thin but cannot be installed in the casing. VOOHU thoroughly explains the selection from three main lines: the choice between integrated magnetic RJ45 and discrete RJ45 + external network transformer, whether the shielding shell is grounded at the bottom (Bob-Smith and chassis ground), tab orientation/sunken plate/low back/

In the traditional industrial automation pyramid, the field layer (sensors, actuators) and the control layer (PLC) have long been separated by various closed, low-speed fieldbuses (such as Profibus, CAN, IO-Link, etc.).This architecture leads to complex c

The network port function and EMC have passed, but it is stuck in the final Hi-Pot voltage test? Starting from the isolation nature of Ethernet transformers, VOOHU dissects the real causes of sparking and excessive leakage current (center tap capacitor withstand voltage, PCB creepage distance, GDT malfunction), and provides a safety selection table for isolation voltage withstand voltage of 1500V~5000V full-range network transformers and integrated magnetic RJ45.
