Pancake slip ring, also known as flat slip ring, is a special kind of slip ring. Its friction pair consists of a contact brush and copper rings. Copper rings are stacked concentrically instead of stacking together. This structure contributes to the ultra-thinness of the flat sliding ring. The pancake sliding ring is therefore particularly suitable for electronic devices with limited space in the axial direction. The sliding pancake ring also plays an important role in the military industry. With our excellent design and manufacturing techniques, JINPAT pancake slip ring is a top-notch choice for military devices.

An example is JINPAT pancake slip rings, which are widely used in radar and satellite communications on the move for vehicle systems and airborne systems. Being ultra-thin and comfortable, JINPAT’s flat slip ring is very competitive in applications with limited axial space. Take a look at the following comparison. JINPAT LPT 000-0510-E2 is a through-hole slip ring designed for radar system. It has the simplest structure and the least number of channels. It integrates only 5 channels of 10A, but its height reaches 72.5 mm. Compared with such a model, the JINPAT LPK000-0410-08 SE 2 flat slip ring is only 36 mm high. The height of the pancake ring is reduced by half. And the height of most models of JINPAT pancake rings is about 36mm.

Due to their one-piece design, JINPAT’s sliding pancake rings have a high degree of protection. The LPK000-0410-08 SE2 has an IP65 rating, while the LPK000-0230-10 SE 2 has an IP 64 rating. Due to the relatively high degree of protection, JINPAT pancake rings can work in difficult working conditions. This feature also makes it very suitable for military applications.
