Rotary platform is an essential simulation equipment to imitate operational environment for the tested devices. And on the rotary table, electrical slip ring is a key component. JINPAT Electronics, as a slip ring manufacturer with over 20 years of experience, has accumulated plenty of experiences in developing slip rings and rotary joints for the simulation platform. There are newly released slip ring models for simulation turntable. Let’s have a look at the features of these JINPAT slip rings.

LPC-0604-07S-01E3 is a lately delivered slip ring model with 5-year production experience. This lately delivered order contains over 100 pieces of custom capsule slip rings. And production volume of this slip ring model is over 1000 pcs. This simulation turntable slip ring integrates 6 4A power channel, and its signal module integrates 1 100M Ethernet slip ring and 1 RS signal slip ring. The total length of this mini size rotary joint is 42mm with a diameter of 20mm. The parameter is 2mm smaller than the standard slip ring with 6 2A channels. In short, it is a powerful integrated capsule slip ring. To facilitate installation on the rotary platform, the channel outlets are on the flank of the slip ring unit on stator side. Most of the simulation rotary platform slip rings take the same form of leads outlet.

Slip rings for rotary platform generally integrate Gigabit Ethernet signal channel to convey analogy signals when the simulation platform rotates. As the key player in transmitting signals for the simulation turntable, there is strict requirement on package loss rate of the Ethernet signal channel. JINPAT Electronics, as an edge-cutting slip ring manufacturer can keep the package loss rate within 1/107.

Another special characteristic on JINPAT multi-axis simulation rotary platform slip ring is through skill and high standard handling technique, user can put 4 slip rings in series at max. This a technical challenge aside from super low package loss. Beside, this custom integrated slip ring also stands out in product life, reliability and electronic performance. JINPAT Electronics wins a lot more clients by this technique strength representative product.

In most circumstances, aside from power and signals, some electromechanical equipment demand 1 to 2 hydraulic pneumatic channels to transmit fluid and gas. A simple combination between rotary union and slip ring will not work. And a brand new integrated slip ring design is needed.

As a professional slip ring manufacturer, JINPAT Electronics is an established slip ring manufacturer in China. And with years of dealing with different applications, JINPAT Electronics has accumulated abundant experience in making custom slip rings. In the past two month, JINPAT Electronics has developed a dozen custom integrated slip rings with 1 to 2 hydraulic/pneumatic channels. To fit with different application end, the structures of these new slip ring models are also different.

Take the integrated slip rings with 2 hydraulic pneumatic channels for example, the most frequently adopted solution is one that join the rotary union with electrical slip ring. LPPL000-0620-E2-02A is a representative integrated slip ring model. There are 6 20A power channel and 1 100M Ethernet channel, and 2 hydraulic pneumatic channels. The fluid and gas channels can transmit compressed air in 10Bar. The slip ring is expected to take up horizontal installation. Client can demand protection grading up to IP67.

Aside from the two-module design, there is another structure where electrical signal module and the hydraulic pneumatic module share the same rotor but have an independent stator respectively. This type of slip ring has advantages in strength of structure and impact endurance. Some integrated models have been put into practice. LPT000-1010-02E3-02A and LPT090-0615-0405-E2-02A are two typical model with Ethernet signal capacity and meantime transmit fluid and gas.

Among integrated hydraulic pneumatic slip rings, those with single channel for gas and fluid are with the simplest structure. This can be done by installing a rotary union within the through bore of a hollow shaft slip ring. LPT000-0340-13S-01A, LPT000-0104-E2-01A and LPT000-01A-0803-12S-04GND are very mature models of such type.

In the age of electronic and mechanical integration, there are increasing numbers of equipment and devices that adopt computer signal like USB signals and Ethernet signals. And as a key component that allowing connecting joints rotate while transmitting signal and power at the same time, slip rings are made to fulfill such mission on the electromechanical system.

JINPAT develops Ethernet slip rings and USB slip rings.

However, in most cases, slip ring with sole capability to transmit USB signals and Ethernet signals is not enough. So integrated slip rings that can mix transmit different signals are invented. Aside from common electric signals, USB2.0 and USB3.0 are typical integration. Some slip ring can integrate USB1.0. Similarly, Gigabit Ethernet and 100M Ethernet can also be integrated transmit. And there is also slip ring solution that combine both USB signals and Ethernet signals.

Let’s look at USB1.0 integrated slip ring, it is coded LPMS-12U-0701-U2-U1. The working voltage is 48V and there is 1 USB2.0 channel and 1 USB1.0 channel. Another 7 1A power channels. From the coding, it is a revised model based on LPMS-12 standard super miniature slip rings. Therefore, it has the same inner structure and size as standard slip ring model. With an outer diameter of 6.5mm and a length of 17.4mm. It is one of JINPAT’s smallest USB2.0 slip ring models. LPMS-05D is even a smaller product.

Compared to USB1.0 slip ring, USB2.0 slip ring has wider applications. Our JINPAT team has developed a USB2.0 slip ring with 8 channels. This is the most multi-channel product of JINPAT slip ring. However, the transmission capacity of 8-channel USB2.0 slip ring is not comparable with USB3.0 slip ring. LPC-30A-0602-01U3-01U2 and LPC-30T-1402-01U2-01U3-E2 are typical slip ring model that transmit both USB2.0 and USB3.0 signals.

The features of Ethernet signals make them very practical for large structure. LPT000-1016-0202-02E3-03U2 is a typical large volume slip ring that integrates USB3.0 signal. The integrated USB3.0 part is installed within the through bore structure.

JINPAT Capsule slip rings are the series with the smallest size, meantime, they have the largest annual production volume. And according to the diameter, the series can be further divided into 3 groups, medium size LPC capsule slip rings (diameter above 20mm), mini size LPM miniature slip rings (diameter between 12.5~20mm) and super mini size LPMS super miniature slip ring (diameter less than 10mm). There are approximately three hundred models in this compact size series. For their great adaptability, they can be installed in many electromechanical systems and the capsule slip rings are highly versatile.

Let’s begin with our smallest slip ring models, LPMS-05D and LPMS-08D, their diameter is the same, 5.5mm, with a total weight no more than 10g. They are the slip ring models with the smallest diameter and the lightest weight. Their annual production volume exceeds 10 thousand pieces. And these super miniature slip rings are adaptable for various application end. Some college students and research experts tend to install these slip rings on some testing equipment. Of course, the two mini-size slip rings are mostly applied in commercial electronic devices.

JINPAT LPM miniature slip ring is slightly larger than the LPMS super miniature slip ring. And with a larger volume, the LPM slip ring can integrate 30 channels at max. The slip ring models of this branch tend to have a diameter between 12.5mm and 16mm. Similar to the former mentioned slip rings, the LPM-18 series, with 18 channels, has a relatively large production volume. JINPT miniature slip rings can be installed in total station, photoelectric pod and other precision optical equipment. And some high end medical devices also need electrical slip ring with compact size and excellent electronic performance.

And the LPC capsule slip ring series is a collection of slip ring with diameter above 20mm. And the most popular model is also with 18 channels, the LPC-18 branch. They are electrical slip rings that can fit in various electronic devices. A typical case is the application on surveillance camera that oversees the factories and schools.

And among JINPAT capsule slip rings, there are many models with over 30 channels. For the number of channels, they have, they can be installed in automated production machines. And since the production volume reduces as the channel numbers increase, JINPAT LPC-56 has less application case. This capsule slip ring model can be installed in automated production machines and also photoelectric pods and radar systems.

As small size electrical slip ring, the compact size slip rings can be applied in thousands of different applications. JINPAT Electronics, with over 20 years of experience in the industry, has put great efforts in enhancing the slip ring series. And we offer customization to help our slip ring products better satisfy different requirements.

In the face of fierce market competition, no matter what kind of products, quality is always the foundation of an enterprise.Quality first is the service principle that JINPAT Electronics has been adhering to for many years, and it is also the basis for JINPAT slip rings to gain good reputation in the market.Behind the high-quality slip ring is the super large-scale product test center of JINPAT Electronics.JINPAT product testing center is divided into two areas: slip ring life test laboratory and product environmental adaptability laboratory, covering a total area of more than 1,000 square meters and having more than 500 sets of various equipment.

In the slip ring life test laboratory, newly developed slip rings and old products after material and structure improvement need to be tested in the test center to obtain final accurate life data.The whole life test cycle of some high life conductive slip rings even exceeds one year.Of course, for conventional and mass-produced products, JINPAT’s quality engineers will also conduct random inspections on a regular basis to ensure that the products received by customers are of the best quality.JINPAT slip ring life testing laboratory has a lot of equipment, which can support nearly 500 products to be tested at the same time, and it is far ahead of other slip ring manufacturers in the industry.JINPAT uses the original method to test the life of the slip ring, because JINPAT Electronics has found that there is no shortcut to improve the quality of the product. Only after years of repeated testing can we design the most suitable structure and key materials.

Environmental testing is also a very important part of the slip ring development process, especially those products with high environmental requirements.Many of JINPAT slip rings will be used in the environment of seawater, high temperature and high dust, so the environmental test is one of the tests that must be carried out before the slip ring leaves the factory.JINPAT environmental simulation laboratory has a variety of test equipment such as high and low temperature boxes, salt spray testing machines, vibration tables and so on. Taking high and low temperature boxes as an example, there are as many as 15 sets of high and low temperature boxes of various specifications, which can complete high and low temperature impact tests between – 100℃ and + 300℃. It is worth mentioning that some test equipment’s turntables use JINPAT’s own slip rings.
