VOOHU Electronics officially launched two new coupler male and female connectors, WHKNZ63YSCAT6a and WHKNZ63CAT6a180, which focus on 10 Gigabit (CAT6A) transmission rate. They adopt industrial-grade metal shell design and support PoE power supply. They are targeted at connection scenarios with high speed and reliability requirements such as industrial Ethernet, outdoor security and PoE front-end. The metal male connector WHKNZ01000FS is an existing product of VOOHU and can be used with two new products. For product selection and technical support, please visit VOOHU's official platform WW

In PoE power system design, the selection of PSE and PD controllers often draws the most attention. However, in real engineering, whether the matching between the power transformer and the LAN Transformer is appropriate directly determines power supply ef

The driver type of an Ethernet PHY chip directly determines system signal integrity, anti-interference capability, and hardware design complexity. Voltage-mode and current-mode PHYs may appear to differ only in signal carrier, but they have fundamental di

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

In audio systems, speakers and amplifiers are often the focus of discussion, while the audio transformer, a crucial component, is frequently overlooked. In reality, it plays an indispensable role in ensuring sound purity, reducing background noise, and ex

In the fields of professional audio, video transmission, and stage lighting control, a seemingly minor connectivity issue can bring a meticulously planned performance or important event to a standstill. Vibration, frequent plugging and unplugging, and com

Nowadays, more and more devices have local area network (LAN) connectivity. To facilitate communication, the simplest solution is to power the devices via a LAN cable (Power over Ethernet), thus eliminating the need for a separate power supply.PoE Transfo

I. Industry Challenges: The Noise Dilemma of BMS Communication In a battery management system (BMS), the stability of the communication link directly determines battery safety and lifespan. Whether it's the complex electromagnetic environment of electric vehicles (EMI sources such as inverters and relays) or the long, multi-module series connections of energy storage systems, both face the following challenges: ▪ High-voltage differential interference (battery packs reach 1000V+) ▪ Common-mode noise causing data distortion ▪ Risk of safety isolation failure Industry needs: Communication magnet

Standard circuit design for POE outdoor lightning protection solution

In today's world, where the vast majority of end-use electronic devices (for consumer electronics, transportation, communications, and industrial) are connected to each other through some form of communication network, the Ethernet protocol is used in many common applications we encounter every day. 1. Industry pain points: limitations of traditional network transformers In the fields of industrial automation, smart cars, and 5G devices, Ethernet transformers are the core components that ensure signal integrity. However, traditional toroidal transformers face three major challenges: 1. Manual

With the rapid development of smart manufacturing and the Industrial Internet of Things (IIoT), industrial communications are moving towards high-speed and intelligent technologies. Industrial automation equipment requires real-time, efficient transmission of large amounts of data to achieve precise control and collaborative operations. Industrial Ethernet fieldbus, with its high speed, high reliability, and strong compatibility, has become the mainstream choice for industrial communications and is widely used in smart manufacturing, smart factories, industrial automation, and other fields. T

In today's world where electronic devices are becoming increasingly sophisticated and complex, electromagnetic compatibility (EMC) has emerged as a critical threshold for product reliability and market competitiveness. Both the weak signals in high-speed
