Two Gas Passage 20mm Hollow Shaft Size Electrical Rotary Union
Description of 3402004 Hollow Shaft Slip Ring
The Senring 3402004 series pneumatic rotary joint is a dual passage rotary joint capable of 360-degree rotation and transmission of 2 passages of compressed air, steam, vacuum, and other gas media. This rotary joint supports 4mm and 6mm air pipes for gas transmission. Furthermore, it supports mixed transmission of various currents ranging from 2A to 800A, while also having the advantages of small size, light weight, low torque, and the ability to transmit multiple gas passages without interference.
This rotary joint is suitable for many industrial applications, such as robotics, automation equipment, and medical devices. Its dual passage design enables it to transmit multiple gas media simultaneously, thereby improving system flexibility and efficiency. Additionally, its small size and lightweight design make installation and maintenance easier.
