Slip rings are critical components that enable the transfer of power and signals in a 360° range, and they are widely used in electromechanical products across various industries. In the field of consumer electronics, slip rings are also employed in certain specialized products such as high-end toys, multi-rotor drones, and stabilizing gimbals.The slip rings used in these products typically have small dimensions and are lightweight. One notable example is the slip ring solution provided by JINPAT forconsumer electronics applications. The JINPAT LPMS ultra-miniature slip ring series, with a diameter usually below 10mm, includes a few customized pancake slip ring products.
As a pioneer among international slip ring manufacturers, JINPAT LPMS ultra-miniature slip ring series currently represents one of the smallest slip rings available in the global market. The smallest product in the series has a diameter of only 5.5mm. If there is a clear demand for even smaller diameter slip rings in the market, JINPAT can develop ultra-miniature slip rings with a diameter of 4.5mm. Presently, the standard LPMS ultra-miniature slip rings offer a maximum number of 15 signal channels and have a diameter not exceeding 7.1mm, with a total wire weight not exceeding 15 grams.
One distinctive feature of JINPAT LPMS ultra-miniature slip rings is their ability to support the mixed transmission of both power and signals. However, they are limited to transmitting relatively simple signals. For more complex signals such as Ethernet or USB, customization is required. Leveraging the advantages of the LPMS series ultra-small diameter,JINPAT has developed numerous signal-integrated slip rings for specialized applications, including USB 2.0, SDI high-definition video signal, and gigabit Ethernet signal slip rings. Among these ultra-miniature customized slip rings application terminals, cruise missiles can be considered the most unique. The slip rings are installed inside the optical-electricturret of the cruise missile to support the transmission of power, SDI, or other signals.
As a weapon that has gained popularity on the battlefield in recent years, cruise missiles are characterized by their portability and precision in striking targets. However, they also impose strict limitations on the size and weight of their components. Therefore, for ultra-miniature slip rings like JINPAT LPMS series, which weigh only a few grams, the optical-electric turret of cruise missiles is an ideal application terminal. Taking the example of the JINPAT LPMS-15 standard slip ring, it can be customized to accommodate SDI, Ethernet, and other signal channels, meeting the transmission requirements of common signals in small optical-electricturrets. Through optimized design, it can also support the operation of small aircraft or cruise missiles at altitudes above 8000 meters. This data is not derived from thin air but is based on conclusions drawn from the summary of various ultra-miniature slip ring cases provided by JINPAT for the consumer electronics industry and other sectors over the years.
