Ethernet slip ring ESET series

gigabit Ethernet1 Gbps100 Mbps

Description
The ESET Series Ethernet through-bore slip ring is a rotating assembly for transferring power, control circuits and data (analog/digital) between stationary inlets and rotating outlets. It offers a 1.5 inch (38.1 mm) through bore for shaft mounting and supports 100Base-T or 1000Base-T Ethernet terminated with RJ45 connectors. The design uses low-wear fiber brush contacts that do not require lubrication. Standard models range from 4 to 22 circuits. Integrated fluid + electrical combinations are available for combined rotary union and slip ring applications.
