Regardless of the industry, technical verification is an important part of the R&D process.
IP68 protection grade is the highest protection level of slip ring. The slip ring that reaches this protection level can work under water for a long time. JINPAT Electronics has developed a number of IP68 protection level under water slip rings
This slip ring has been improved from the standard slip ring LPC-18. In addition to the internal and external structure changes, the protection level reaches IP68, and its current circuit becomes 6 circuits 5A. The IP68 slip ring must have very strong hardness and superior sealing for the purpose of working normally for hundreds of meters under water. This slip ring adopts a stainless steel outer casing, and waterproof rubber is attached to the outer openings, and the metal and waterproof PG joints are used for the rotor and stator terminals. In addition, due to the relatively large diameter of the wire used, a large amount of waterproof glue is attached to the joint of the PG joint. To maintain the durability of the wire, the outer layer is wrapped with a silicone tube, and at the end of the silicone tube, a large amount of waterproof glue is also used, which can prevent the water flowing under the high pressure into the conductive slip ring.
