28-Channel IP67 Waterproof Gigabit Ethernet Slip Ring with 50mm Large Aperture and Stainless Steel Housing

IP67 means complete dust protection (Level 6) and immersion in 1 meter of water for 30 minutes without damage (Level 7). This allows it to withstand heavy rain, high-pressure water jets, splashing waves, and accidental immersion, making it suitable for extreme environments such as decks, docks, and mines.

Yes. 13 channels at full load can provide a total current capacity of 975A. Based on a common 380V voltage, the theoretical transmission power can reach over 370kW, sufficient to drive large rotating equipment of hundreds of kilowatts. In practical applications, it is necessary to ensure that the power supply capacity and heat dissipation conditions are matched.

The channel has independent shielding and impedance matching design internally. The IP67 sealing treatment is located on the external housing, and the two do not interfere with each other. Rigorous testing ensures that while meeting the highest protection level, the gigabit network's transmission rate, bit error rate, and other performance indicators still comply with the IEEE 802.3 standard.

The 50mm inner hole can accommodate:

• Hydraulic pipes: Multiple high-pressure oil pipes
• Cable bundles: Multiple thick power cables
• Fiber optic/network cables: Multiple data cables
• Mechanical spindle: A through hole for the rotating shaft of equipment
• Combined piping: Allows for the simultaneous passage of pneumatic, hydraulic, and electrical pipelines

20rpm is an optimized value for heavy-duty conditions. For higher speeds (such as 100rpm), we can adjust the dynamic balance and sealing design. 75A is the standard configuration; for 100A, 200A, or even higher currents, customized high-current modules are available.
