Ethernet Electrical Slip Ring All of us should know that, slip ring can be a rotating joint that could connect with two devices and transmit signal under 360 degree rotating process. Conductive slip ring can transfer many different types of signal, say Ethernet, USB, RS, Canbus, FireWire, thermcouple, servo motor, encoder, strain gauge and so on. Ethernet provides effective solution between HD camera and control rotating platform to transmit HDTV standard resolution 1920*1080 all real-time image for HD video monitoring system. Ethernet slip ring is specially designed for 250MHz frequency signal which used to transmit 100M/1000M Ethernet signal, also can combine with electrical power, fiber signal, high frequency and signal channel with the feature of stable transmission, low insertion loss, no lost package, no string code, etc. According to the monitoring equipment installation space, the suitable slip ring type could choose through hole slip ring or capsule slip ring with different size. The max through hole size could be designed to 80mm, more size could be optional. However, normally we suggest end user to accept smaller diameter, because it could pass Ethernet signal well. Ethernet slip ring adopt CAT5 or CAT6 class line, the cable length can be up to 2m. This series of slip ring structure reference international Ethernet standard and protocol requirements for design which largely reduce unshielded twisted pair for crosstalk and attenuation through signal processing. Generally use 1G full-duplex and half duplex interfance mode.
