Precision conductive slip rings can be classified into many types, with different manufacturers having different standards and definitions. However, generally speaking, the classification methods are mostly similar. Firstly, they can be categorized based on structure. This type of precision slip ring generally refers to conductive slip rings with high internal space utilization and very small volume, such as the LPMS series slip rings from JINPAT. Another category is the technically intensive precision slip rings, which include fiber optic slip rings, high-frequency slip rings, etc., and are included due to their high development difficulty. Then, they can also be classified based on the functions of the slip rings. This type of precision slip ring not only has the ability to transmit power but also has one or more functions such as gas, liquid, or signal transmission.

As a professional and experienced slip ring manufacturer, JINPAT has been in the industry for nearly 30 years. As early as 2002, they established their own technology R&D center, focusing on developing independent R&D capabilities. They also have extensive experience in the development of precision slip rings. As for fiber optic slip rings, which have very high performance and excellent application prospects, JINPAT started its independent R&D early. In 2009, JINPAT successfully developed fiber optic slip rings with independent intellectual property rights.

As a kind of precision slip rings, fiber optic slip rings have their own uniqueness. First, fiber optic slip rings do not transmit electricity, gas, liquids or other media; they only transmit light. For example, among the seven colors of light commonly seen in everyday life – red, orange, yellow, green, blue, indigo and violet – some of the light can be transmitted through fiber optic contact rings at their respective operating wavelengths. The fiber optic slip rings developed by JINPAT use single-mode or multi-mode fibers covering the wavelength range from 650 nm to 1650 nm, corresponding to visible light and near-infrared radiation.

Since transmission is via fiber optics, fiber optic slip rings do not require electronic components, but only optical components. Since these optical components must be optically coupled to single-mode fibers with core diameters as small as 9 or 10 micrometers and multi-mode fibers with core diameters of 50 or 62.5 micrometers, the volume is extremely small, which requires extremely high mounting accuracy. This makes it very difficult to fabricate and machine fiber optic slip rings, which is also the main reason for the high accuracy of fiber optic slip rings. Due to the high processing complexity of internal components and extremely high requirements for precision manufacturing technology, there are not many slip ring companies, such as JINPAT, that can independently develop and manufacture fiber optic slip rings.
