Precision conductive slip rings can be classified into many types, with different manufacturers using different standards and definitions. In general, however, the classification methods are largely similar. First, they can be classified by structure. This type of precision slip ring usually includes conductive slip rings with high internal space utilization and very low volume, such as JINPAT’s LPMS series slip rings. Another category is technically complex precision slip rings, which include fiber optic slip rings, high-frequency slip rings, etc., and are included in this category because of the high complexity of their development. In addition, they can also be categorized based on the function of the slip rings. This type of precision slip rings is not only capable of transmitting energy, 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.
