Two Passage Electrical Rotary Union Support Transmit Mixed Power And Signals
Description of 3402004 Hollow Shaft Slip Ring
The SenRing 3402004 series pneumatic rotary joint is a dual-channel rotary joint that can rotate 360 degrees to transmit two channels of compressed air, steam, vacuum, and other gas media. It is suitable for 4mm and 6mm air pipes. In addition, this 3402 series rotary pneumatic joint can not only transmit gas but also mix and transmit various electric currents ranging from 2A to 800A. This rotary joint is characterized by its small size, light weight, low torque, and multiple gas passages that do not interfere with each other.
one example of an industrial application where low torque is important is in robotics. In robotic systems, low torque rotary joints are often used to transmit compressed air, vacuum, and other gases to the robotic arm, grippers, and other end-effectors. The low torque reduces the energy required to rotate the robotic arm and perform tasks, which results in lower power consumption and less wear and tear on the system's components.
Additionally, low torque rotary joints can improve the precision and accuracy of the robotic system, which is essential for performing tasks that require precise movement and control. For example, in assembly line applications, robotic arms need to be able to pick up and place small components with precision and accuracy. Any excess torque in the rotary joint can cause the arm to overshoot the target, leading to errors in the assembly process.
Therefore, by using low torque rotary joints in robotic applications, overall system efficiency can be improved, resulting in better performance, lower energy costs, and reduced maintenance expenses.
