High-frequency slip rings are a common typeof rotary joint used to transmit high-speed and high-frequency signals or powerin various mechanical systems, such as radar, satellite communications, medicalequipment, robots, and aerospace equipment. The device consists of a rotor anda stator, which are electrically connected by conductive carbon brushes or metalbrush strips. High-speed rotation and high frequency require the brush orcarbon brush to have good conductivity, wear resistance, and stability. At thesame time, precision manufacturing and assembly technology can ensure lowcontact resistance and excellent signal transmission performance between therotor and stator.

The future development direction ofhigh-frequency slip rings includes high-speed and high-frequency, multi-channeltransmission, high reliability, contactless transmission, and intelligence.These directions require high-frequency slip rings to have higher rotationalspeed and transmission frequency, more complex structure and highermanufacturing technology, higher reliability and stability, adoption ofcontactless transmission technology, and intelligent connection and interactionwith other equipment and systems to improve the efficiency and automation ofthe entire system.

The high-frequency slip ring productslaunched by JINPAT mainly include the LPCC series and the LPHF series. The LPCCseries of high-frequency slip rings are single-path slip rings with a smallerdiameter, which usually need to be integrated with capsule slip rings or smallaperture through-hole slip rings. When using a 75Ω coaxial cable, this seriesof high-frequency slip rings can be used to transmit SDI high-definition videosignals, supporting up to 12G-SDI signals. When using a 50Ω coaxial cable, itcan support RF signals with a maximum peak power of only 3KW. Suchhigh-frequency slip ring products are widely used in large stabilizing pan-tiltfor auxiliary high-definition cameras, spherical rotatable high-definitionvideo surveillance cameras on the street, as well as weapon equipment such asoptoelectronic turrets and machine vision equipment.

The LPHF series of high-frequency sliprings have higher capability and can support RF signal transmission with amaximum peak power of 30KW. This type of high-frequency slip rings is commonlyused in radar with rotating panels and some special medical equipment fields.The high-frequency slip rings used in medical equipment have a fixed frequencyband, while the high-frequency integrated slip rings used in radar need to beequipped with high-frequency slip rings that support the correspondingwavelength.

JINPAT updates the integrated LPCC and LPHFhigh-frequency slip ring products every year to meet the ever-changing marketand application needs. All high-frequency slip ring products are independentlydeveloped and manufactured by JINPAT, and they are trustworthy.
