A slip ring with a hole in the center can be called a conductive slip ring with a via hole. According to different functions, it can be divided into Ethernet via slip ring, disc via slip ring, USB via slip ring, etc. Mainly used to transmit power, precision signals, etc., with low torque, low noise, long life, maintenance-free and so on. Also known as hollow shaft slip ring, hole slip ring, etc.

The applications of through-hole slip rings are mainly used where power, signal or data must be transmitted and 360 unrestricted continuous rotation is required. The manufacturing principle and process are similar to other slip rings, and the contacts of the electric ring are contacted as follows. brush. The through-hole slip ring developed by Chihong Technology basically adopts the fiber brush bundle technology, which can better ensure the transmission of current, signal, data, etc. from the static position to the moving position. The basic parameters of the through-hole slip ring include inner diameter, outer diameter, number of turns, current, voltage, speed, length, etc.

Thin Via Conductive Slip Ring

In principle, any size via hole slip ring can be customized arbitrarily, but with the development and maturity of the industry, a relatively fixed and popular standard size has been formed, such as the existing via hole inner diameter size. market. - Chihong Technology's hole slip rings include 12mm, 20mm, 25mm, 38mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 120mm, etc. The number of turns of an electric slip ring is a decisive factor in evaluating the price of a slip ring, and one of them is usually 2 to 56 rings. The more cycles there are, the more complex and varied the manufacturing process becomes. You need to consider. The working speed generally refers to the maximum speed per minute. Working at the maximum speed for a long time will shorten the life of the slip ring. Exceeding the maximum speed will not only affect the life, but also greatly affect the transmission power and signal. The accuracy of the data can also add noise and cause internal damage. Both current and voltage parameters are limit values and generally do not reach their nominal values during normal operation.

Since the hole slip ring is a general term judged from its structure, it is widely used in automation fields such as robots, robotic arms, packaging equipment, filling equipment, and testing equipment. However, in current industrial systems, through-hole slip rings usually require custom production, so the unit price is higher than that of cap-type slip rings.
