DHK025-4-20A Standard 25 mm through hole conductive slip ring 4channels 20A

Through hole conductive slip ring DHK025 series

DHK025-4-20A series through hole conductive slip ring has a middle hole of 25.4mm and an outer diameter of 78mm. It is suitable for rotating electromechanical systems with a diameter less than 25.4mm. The power is 4 channels and 20A/channel. It is also called a hollow shaft slip ring. The shell is made of special engineering plastics, and can be made of aluminum alloy or stainless steel. In order to stably transmit power or signals to electromechanical systems that require 360-degree rotation, it can also be designed in combination with air rotary joints, liquid rotary joints, fiber optic slip rings, etc. to form a multifunctional hybrid slip ring.

As precision conductive slip rings, they are widely used in intelligent visual robots, packaging machines, filling machines, blanking machines, sampling machines, small amusement machines and other automation equipment.
