Ethernet Slip Ring is a device that allows Ethernet signals to be transmitted through a rotating assembly. This device is typically used in applications where it is not possible or practical to run Ethernet cables, such as in an application where the cables would have to travel through a hazardous area. It converts the regular Ethernet signals into rotary signals, which are then transmitted through the rotating assembly.
There is a growing trend in the industry for Ethernet slip rings. Ethernet slip rings are currently being used to interconnect computer networks. A slip ring is a transmission device that uses a counter-rotating encircling belt to transfer power and data between two or more devices.
Senripgrid Conductive Slip Ring has the following characteristics Direct unplugging of the RJ45 connector Upon reaching eight simultaneous ports, follow the standard cable connection method Work with either copper or gas-liquor joints Transmission to the external network (10M, 100M, 1Km Base T).
