Today's society is inseparable from the Internet. Large industrial automation equipment, small watches and phones, all of which are inseparable from the Internet. It can be said that we are now living in an era of Internet information. As an indispensable electrical component of modern automatic equipment, conductive slip rings have also introduced Ethernet slip rings in order to keep up with the times. So what is an Ethernet slip ring, and what is the working principle of an Ethernet slip ring? Today, the editor of Jiachi conductive slip ring will tell you what is an Ethernet slip ring, and what is the reason for the work of the Ethernet slip ring.图片

First of all, let's talk about what is an Ethernet slip ring. Everyone knows that a conductive slip ring is an electrical component that can rotate and transmit all media such as current, signal, gas, etc., then the Ethernet slip ring is also specially used to transmit Ethernet signals. Conductive slip rings, collector rings, slip rings, electrical rotary joints. The Ethernet slip ring is specially designed for 250Mhz frequency signals, used to transmit 100M/1000M Ethernet signals, can mix electrical power channels and signal channels, and can transmit multi-channel low-frequency signals and currents at the same time, with stable transmission, no packet loss, Electrical rotary joints with advantages such as non-string code, low return loss, and low insertion loss. To put it bluntly, an Ethernet slip ring is a conductive slip ring specially developed for equipment that needs to rotate to transmit network signals. It has all the functions of a conventional conductive slip ring, and also has the special function of transmitting network signals, which can ensure the 360-degree uninterrupted rotation of automation equipment while transmitting industrial Ethernet signals.

So how does such a powerful Ethernet slip ring work? In fact, the working principle of the Ethernet slip ring is the same as that of the ordinary conductive slip ring. Common conductive slip rings and Ethernet slip rings consist of a stator and a rotor. The design structure of the stator and rotor is a precise superposition of single channels. Design the number of superimposed circuits according to the operational requirements. During assembly, the stator channels correspond to the rotor channels to form channels between the rotor and the stator. The electrical performance of each channel is independent of each other. Perhaps the biggest difference between Ethernet slip rings and ordinary conductive slip rings is the difference in internal contact materials. Many people may tell you that the contact materials are precious metals, but this is just a rhetoric. The internal contact material of the common conductive slip ring that transmits current is only pure copper, and the surface is subjected to simple electroplating treatment. However, in order to ensure the smooth network signal, the internal contact material of the Ethernet slip ring is generally copper alloy surface gold-plated, while the Ethernet slip ring is gold-plated. The inside of the network slip ring also needs to be shielded to prevent signal interference.

In general, the Ethernet slip ring is still one of the conductive slip rings, but the Ethernet slip ring transmits industrial Ethernet signals. Compared with the control signal transmitted by the ordinary conductive slip ring, the control signal transmitted by the Ethernet slip ring is much more advanced. The material and production process of the ring are much more complicated.
