Conductive Slip Rings in Aerospace Equipment by JINPAT

Conductive slip rings in aerospace equipment are primarily used to enable high-precision and high-reliability signal and power transmission. These slip rings must possess exceptional environmental adaptability, capable of stable operation under extreme conditions, such as multi-channel and high-current handling capabilities and adaptability to high-voltage environments, ensuring stability during spacecraft launch and high-power operation. They support multiple signal types, including USB 3.0, 10G Ethernet, HDMI, and SDI, enabling seamless connectivity for high-speed data transmission in aerospace systems. With protection ratings up to IP68, they function in extreme humidity, high or low pressure, adapting to both the vacuum of space and harsh underwater conditions. They can withstand a temperature range from -55℃ to +250℃, accommodating the extremes from cold space to high-heat environments, and support speeds up to 30,000 RPM with a minimum torque of 0.02 N.m, ensuring high-speed stability in aerospace equipment.

For spacecraft, slip rings are not merely devices for current and signal transmission but are essential components that ensure precise control and efficient operation of equipment. JINPAT, a specialized developer of conductive slip rings for aerospace, has developed nearly a hundred models specifically for aerospace applications. These include standard models adapted from the aviation industry and highly customized models tailored to the industry's unique requirements. The most widely used standard slip rings for aviation equipment are primarily LPS Separate slip rings, often installed in various mechanical instruments on aircraft, such as gyroscopes and horizon indicators. As glass cockpits and precise electronic instruments become more common, the use of these slip rings in aviation instruments will likely diminish.

In comparison with standard split slip rings, JINPAT’s custom LPS models include various products developed for aerospace applications. Among these, the most representative model is the LPS095-0203-30S, a typical low-power slip ring designed for aviation communication systems, with a power ring operating at just 28 VAC and a signal ring minimum working voltage as low as 1 VAC.

Many commercial aircraft also feature built-in entertainment systems, such as retractable remote control reels for multimedia entertainment systems on the backs of seats. JINPAT’s LPMS-06B-U2 is a specialized slip ring developed specifically for these reels. Additionally, some high-end private aircraft integrate multi-dimensional VR systems, and JINPAT has developed several HDMI-integrated slip rings for high-definition video signal transmission to support these advanced VR devices.
