The design of disc slip ring is very different from the hollow shaft cover type slip ring, the copper ring is arranged in one plane using concentric circle arrangement method, using the contact of shrapnel and copper ring, this design allows it to occupy the overall height of the machines, and the equipment cost is very low, this characteristic allows it to be installed in many mechanical and electrical systems with limited axial space. Jinpei’s small disc slip rings are generally made of PCB as the main material, while the medium and large rings are made of Bakelite, and their height can be maintained within 10mm without the addition of housing and no more than 30mm with the addition of housing.
LPK346-0210 and LPK190-0210 are the latest type of PCB slip rings with housing by Jinpei Electronics, these two products are specially designed for medium and large automatic textile machines, both of them combine only 2 channels of 10A current, their height is 25.5mm and 20.8mm respectively, height tolerance value is ±0.3~0.5mm, their outside diameters are 547mm and 308mm respectively. 547 mm and 308 mm respectively.
