JINPAT Pancake Slip Rings are coded as the JINPAT LPK slip ring series. They are slip rings developed for applications with restricted vertical space. Pancake slip ring is a variation from through bore slip ring, keeping a central hole in the slip ring unit. Given the shape of a short cylinder, a pancake slip ring resembles a pancake or a disk, so it is also known as flat slip ring and disk slip ring.
The structure of the pancake slip ring is quite different from the other types. The slip ring rings lies concentrically to each other, just like the soundtrack on a disk. And this structure gives JINPAT pancake slip ring an excellent heat dissipation performance. Minimum thickness down to 5.4mm. Its super thinness makes it like a duck to water in devices with limited vertical space.
JINPAT Pancake slip rings can be further categorized into integrated pancake slip ring and a separate pancake slip ring. The integrated pancake slip ring is a whole unit with housing to provide more protection to the slip ring unit while the separate pancake slip ring is more space-saving and handy for applications with more limiting space in sacrifice of protection grading.Talk to our JINPAT team to work out a custom solution for you!
JINPAT Electronics adopt precious metal as contact material. Besides, the pancake slip ring takes up advanced fiber brush techniques to ensure a reliable contact with low friction, low electrical noise and low debris. Features as such make the 360-rotation extremely smooth and endurable for JINPAT pancake slip rings. Our flat slip ring products is able to carry a safe and accurate power and signal transmission while enjoying a long service life.
