RJ45 Connector

In industrial communication systems, the selection of physical layer interfaces directly affects the signal integrity, reliability, and system cost of bus nodes. From multi‑node interconnection in PLC control cabinets, to lightning protection in outdoor s

1、 Device Introduction A current transformer (CT) is a device used to measure and protect the current in a circuit. It converts high current into low current through the principle of electromagnetic induction for the purpose of measuring and protecting ci

When choosing a network transformer, you only look at speed, packaging, and PoE current, but the prototype repeatedly overturns in negotiation, packet loss, radiated emission, and temperature rise? The problem often lies in the few manual parameters that are skipped. VOOHU explains the five most critical parameters of the network transformer data manual - open-circuit inductance OCL, insertion loss, return loss, common mode rejection ratio CMRR, and DC resistance DCR - one by one: which test bench faults each corresponds to, how to read the numbers, and a quick checklist for selection based on

In today's digital age, network interfaces are key components that connect devices to the network, and their importance is self-evident. Whether it is a personal computer, server or various network devices, network interfaces play an indispensable role. T
