A slip ring, also known as a collector ring in the military and shipbuilding industries, is primarily used in these two major sectors. When distinguishing slip rings, we can categorize them based on their structure, modules, and functions. Differentiation can be made based on the platform of installation, such as aircraft-mounted slip rings for airplanes, vehicle-mounted slip rings for automobiles, and ship-mounted slip rings for vessels.

Regarding functional distinctions, the most basic slip rings support only power transmission and are produced in very limited quantities. Some slip rings, on the other hand, possess the capability to simultaneously transmit power and electrical signals. These products are typically customized to meet specific requirements. Due to the fact that slip rings can support over 30 different signal types, slip rings that integrate power and electrical signal transmission are currently the most widely produced type.

Within the signals transmitted by slip rings, high-frequency signals and optical fiber signals are somewhat unique.Both of these signal types require slip rings with corresponding functionalities for transmission. High-frequency slip rings can support up to four channels,with frequencies ranging from 3GHz to 40GHz. Optical fiber slip rings come in both multi-mode and single-mode varieties, with the highest number of channels reaching dozens. Currently, JINPAT has the ability to mass-produce optical fiber slip rings with up to 10 channels, meeting the demands of the majority of slip ring applications for optical fiber.

Slip rings that integrate high-frequency slip rings are typically used in radar systems, electronic warfare, and satellite communication systems, facilitating signal transmission between antennas and bases. Slip rings that integrate optical fiber, known as electro-optical slip rings, offer strong interference resistance and high signal transmission bandwidth, making them a preferred choice for many popular industry devices.

One very common application terminal for slip rings is electro-optical equipment, such as electro-optical turntables.Slip rings used in this field or other electro-optical devices are also referred to as electro-optical equipment slip rings. It’s important to differentiate them from slip rings that integrate electro-optical components.These electro-optical equipment slip rings from JINPAT often incorporate SDI signals. However, with the widespread adoption of optical communication technology in various sectors, optical fiber slip rings may also appear in electro-optical equipment slip rings as signal modules in the future.

In addition to products that integrate power, standard electrical signals, high-frequency signals, and optical signals, some slip rings also incorporate pneumatic and hydraulic modules for transmitting oil, water, steam, and other gases. These slip rings can be categorized as pneumatic and hydraulic slip rings, or even pneumatic and hydraulic electro-optical slip rings when optical signals are involved. JINPAT offers a variety of slip ring products with integrated pneumatic and hydraulic modules, allowing customers to select the most suitable slip ring based on their specific needs.

Since the advent of optical fiber communication, it has been widely used in various fields due to its outstanding performance. In conventional optical fiber communication, optical signals are transmitted statically through optical cables, and their transmission distance is influenced by single-mode or multi-mode optical fibers. However, with the widespread application of optical fiber technology in traditional manufacturing and other industrial equipment, the demand for dynamic transmission scenarios,such as 360° rotational optical signal transmission, is increasing. In such cases, optical fiber slip rings have become a critical component to support optical signal transmission.

Similar to traditional electrical slip rings, optical fiber slip rings consist of a rotor and a stator. The difference is that the stator of the optical fiber slip ring is designed with a non-contact structure, which incorporates prisms or other optical elements responsible for transmitting signals from the rotor end to the stator end. When integrated with electrical slip rings or pneumatic slip rings, optoelectronic integrated slip rings have the combined transmission capability of power, electrical signals, pneumatic signals, and optical signals. This integrated solution is highly popular in manufacturing and other traditional industries.

As a leader in this field, JINPAT has always focused on independent research and development capabilities. In terms of independently developing optical fiber slip rings, JINPAT has been at the forefront compared to non-specialized optical fiber slip ring manufacturers.They are currently capable of independently supplying optical fiber slip rings with up to 10 channels. This enables JINPAT to meet the optical fiber slip ring requirements of almost all optoelectronic integrated slip rings and gives them a competitive advantage in terms of cost-effectiveness, delivery lead time, and after-sales response time. In the competitive slip ring market, having strongin-house research and development capabilities for optical fiber slip rings undoubtedly places JINPAT in a leading position.

Every year, JINPAT delivers thousands of optoelectronic integrated slip rings to customers, with small and medium-sized products based on capsule and hollow-shaft slip rings comprising the majority. Therefore, the update frequency of these two product categories is relatively high. Recently, JINPAT has also introduced a series of small-scale optoelectronic integrated slip ring products. For example, LPC-12YT-0405-FO01 is a relatively simple product with 4channels for 5A current paths and 1 single-mode optical fiber slip ring. On the other hand, LPC-0505-1102-HD01-FO01 is more complex and integrates 5 channels for 5A current paths, 11 channels for 2A current paths, and 1 HD-SDI high-definition signal path, with the optical fiber slip ring in this model also being a single-mode product. These new products further expand JINPAT’ product line to meet the diverse needs of different customers.

In the product series of JINPAT, the separated slip rings are assigned with the LPS code. Due to structural limitations, their application field is very specific and limited. Therefore,the number of standard product models in this series is relatively small. As for the products with 3, 4, 6, 8, 12, and 24 channels, the separated slip rings have a significant structural difference from other types of slip rings. They have no shell, and the brushes and copper rings of the fixed and rotating parts are both exposed. Such a characteristic determines that they can only be installed in some enclosed instruments or equipment with good protection measures.

 

Aircraft equipment requires a large number of slip rings, such as radar, satellite antennas, and aviation instruments represented by attitude indicators, horizon gyroscopes, navigation balls, and heading gyroscopes. Among these aviation instruments, the separated slip rings are mainly used, except for some ultra-miniature slip rings. For example, LPS-12A,a separated slip ring, was originally designed according to the needs of aviation instruments, so it can be directly installed in attitude indicators,horizon gyroscopes, and navigation balls.

 

In addition to standard products like LPS-12A, there are also many aviation instruments that require customized separated slip rings, such as lengthening the brush wires or reducing the core shaft diameter, etc. Therefore, specialized separated slip rings need to be customized based on actual conditions. In the product cases provided by JINPAT for the aviation instrument equipment field, the vast majority are based on standard products like LPS-12A, and there are few large-scale customized products. The specialized separated slip rings provided by JINPAT for the aviation equipment field are installed on aviation communication equipment, not instruments.

 

IPS095-0203-30S is the most representative customized separated slip ring provided by JINPAT for aviation communication equipment. Due to the structural limitations of the separated series standard slip rings, the highest voltage they can support does not exceed 240VAC. When applied in the dry aviation field, the actual working voltage of this product is basically below 48VAC. Therefore, this product is also a weak electric product with a very low designed working voltage. The rotor through-hole diameter of the LPS095-0203-30S slip ring reaches 95mm, the outer diameter is 18mm, and the height is 85mm. In terms of volume, it can be regarded as a giant among weak electric separated slip rings.

The high frequency slip ring products of JINPAT are divided into two series. The LPCC series with a single channel has a smaller diameter and is usually integrated with capsule slip rings with small apertures. When using a 75Ω coaxial cable, this series of slip rings can be used to transmit SDI high-definition video signals, and currently, the highest supported signal is 12G-SDI. When its cable is replaced with a 50Ω coaxial cable, this series of high frequency slip rings can also transmit radio frequency (RF) signals. However, due to its small size, it can only support RF signals with a maximum peak power of 3KW. The other series of high frequency slip rings, LPHF, has higher capacity and can support RF signal transmission with a maximum peak power of 30KW.

LPCC series high frequency slip ring products can be integrated with 75Ω cables to become slip rings for SDI high-definition video signal transmission. These products usually use capsule slip rings or small through-hole slip rings, except for the LPC-1C series standard high frequency integrated slip rings developed from the LPC-T series products. As long as the LPCC high frequency slip rings integrated with 75Ω cables are used, whether they are hollow shafts or capsule, they can be customized for equipment that requires video signal transmission. These devices include large stabilizing platforms for auxiliary high-definition cameras and spherical, rotatable high-definition video surveillance cameras on the streets,as well as electro-optical turrets and machine vision equipment installed on some weapon systems.

The LPHF series of high frequency slip rings have a wider range of applications. The most typical applications include radar with rotating panels and some special medical devices. The high frequency slip rings used in medical equipment have fixed bands, while the high frequency integrated slip rings used in radar need to be equipped with slip rings that support the corresponding wavelengths.

JINPAT updates the integrated LPCC and LPHF high frequency slip ring products every year to meet the needs of most mainstream application terminals for high-definition video and RF signal transmission. All high frequency slip ring products are independently developed and produced by JINPAT. This makes JINPAT high frequency integrated slip rings not only have a fast delivery speed but also ensures quality.

Among the largest annual production of carbon brush slip ring types offered by JINPAT are those designed for offshore crane applications, quay crane drum applications,heavy-duty port crane operations, large-scale mining machinery, specialized explosion-proof equipment, suspension-type electric propulsion systems, and rotating restaurant stage applications. Within this range, some models are solely focused on power transmission capabilities, while others incorporate gas, liquid, and fiber optic slip rings, as well as optoelectronic signal modules, making them multifunctional products.

As a pioneer in the slip ring industry, JINPAT manufactures dozens of large carbon brush slip rings each year. Recently, they have introduced several new customized carbon brush slip ring models. Let’s take a closer look at these products.

First, we have a pure power transmission ring designed for offshore cranes, bearing the product model LPA000-09800-03200-01PE.This product integrates 9 channels of 800A and 3 channels of 200A current,along with 1 grounding channel. The voltage for the 800A and grounding lines is 380VAC, while the 200A section operates at 250VAC. What sets this product apart is its unique rotor placement below the slip ring, a departure from the typical configuration where most carbon brush slip rings have their rotors installed either facing up or in a horizontal orientation.

Another latest model from JINPAT is the LPT000-06160-0350-0420-01PE-08FO. This product employs a traditional stacked structure with an outer diameter of only 300mm, placing it outside the category of high-current slip rings. It represents a quintessential optoelectronic signal integrated carbon brush slip ring. The electrical slip ring section consists of 6 channels of 160A, 3 channels of 50A, 4 channels of 20A, and 1 grounding channel. Additionally, it features an 8-channel single-mode fiber optic slip ring capable of transmitting data over considerable distances. The160A current channel in this slip ring operates at an impressive voltage of 3300VAC, allowing for lossless power transmission over extended distances.

A slip ring, also known as a rotary electrical connector or rotary joint, is a crucial component in packaging machinery used for transmitting power, signals, and data, making it essential for the smooth operation of packaging equipment. Recently, JINPAT has developed a groundbreaking slip ring that can replace KUEBLER’s products in the field of packaging machinery, offering the following features and functionalities:

One of the primary functions of slip rings in packaging machinery is power transmission. They allow the transfer of electrical power from the stationary parts to the rotating components such as turntables and reels, ensuring the continuous operation of these rotating parts without being limited by cables. This seamless power transmission is vital for the efficient functioning of packaging machinery. JINPAT latest product, the SR085-30-06-04-12302-V100, similar to the hollow shaft slip ring 030 series,offers modular combination of ring circuits, with users being able to choose from 1 to 10 channels. Additionally, this slip ring employs a screw-type wiring method, eliminating the need for external wires, thus significantly reducing space constraints.

Packaging machinery typically requires the transmission of various control signals and data to ensure precise operation and monitoring. Slip rings play a crucial role in this regard by ensuring seamless communication between the rotating and stationary parts, facilitating precise control of the machinery. It is imperative to select highly reliable slip rings to ensure stable operation even under high-speed, high-load, and continuous running conditions. JINPAT SR085-30-06-04-12302-V100 slip ring features an aluminum alloy sandblasted housing, offering excellent wear resistance, high-temperature tolerance, and a long lifespan, ensuring the stability of packaging machinery.

Slip rings are indispensable components in packaging machinery, ensuring the smooth operation of the machines. Therefore,the design and selection of slip rings must be tailored to specific application requirements to meet the unique demands of different packaging machinery.Different packaging machinery typically requires different characteristics,such as varying outer diameters, conductive materials, channel numbers, and rated currents. As a professional slip ring manufacturer, JINPAT actively collaborate with customers to design and produce slip rings according to their specific needs, ensuring the efficient operation of their machinery.

Mechanical laser radar is a widely used sensor technology for distance measurement, 3D modeling, and environmental sensing. Their operation involves the emission and reception of laser beams,often requiring rotating components to scan the surrounding environment. To achieve continuous rotation and transmit power and data signals, mechanical laser radar typically relies on electric slip rings or optical fiber slip rings to support the transmission of power signals.

One notable feature of many laser radars on the market is that their operating wavelengths align with the optical signal bands that optical fiber slip rings can transmit. This makes solving the signal transmission problem for mechanical laser radar relatively straightforward. For instance, most optical fiber slip rings developed by JINPAT support operating wavelengths ranging from 650 nanometers to 1650 nanometers, with only a few models operating within the 850 nanometers to 1550 nanometers range. These bands cover almost all mainstream laser radar operating wavelength ranges.Additionally, JINPAT developed optical fiber slip rings possess excellentel ectrical characteristics and must be capable of transmitting high current and high-frequency signals to meet the power supply and data transmission requirements of laser radar.

For mechanical laser radar, the generated data volume is relatively small, and there is no need to transmit data over long distances. Since mechanical laser radar typically requires continuous operation for extended periods, slip rings must have high durability and stability to minimize maintenance needs. Therefore, using single-channel multi mode optical fiber slip rings can effectively address the issue of laser radar signal transmission. This approach has two distinct advantages: one is better alignment with the working wavelength range of laser radar, and the other is that optical fiber slip rings have an extremely long lifespan, capable of enduring hundreds of millions of rotations, fully meeting the long-termmaintenance-free requirements of laser radar.
Once the signal transmission issue is resolved through optical fiber slip rings, the electrical transmission problem becomes simpler. The mechanical design of the slip rings must align with the mechanical structure of the laser radar to ensure stability during installation and connection. A reasonable mechanical design helps reduce friction and wear,extending the lifespan of the slip rings. Using traditional electro-optical integrated slip rings may result in insufficient lifespan and could increase the volume of the laser radar, affecting its stability. In terms of rotary conductive solutions, as a specialized slip ring manufacturer, JINPAT provides wireless coil power supply solutions.

In conclusion, selecting the appropriate slip rings for mechanical laser radar depends on the specific requirements of the radar. Different models and manufacturers of laser radar may require different types of slip rings to ensure their performance and reliability.Therefore, the choice of slip rings should be made based on a comprehensive consideration of these factors. Feel free to consult JINPAT, and we will provide high-quality solutions.
