SNK Series Pancake Slip Rings(Min. Thickness 6.5mm)

Produced by Senring developed pancake slip ring,As another form of though hole slip rings, pancake slip rings are designed for somewhere vertical space is limited while horizontal space is less restrictive. Special high vacuum sealing technology & precious metal brush ensure the high reliability transmitting and rotating performance of slip ring. With many advantages such as low torque ,low friction, low electrical noise and long life, pancake slip rings are mainly applied to transmit precise signal together with power, also could be combined with fluid media transmitting(such as hydraulic or pneumatic..)

  1. 12 rings pancake slip ring
  2. PCB slip ring
Features
SNK series specailly designed for the rotary systems where limited vertical space
Min.thickness 6.5mm,OD100mm,through hole with many hole sizes or solid optional
Advanced spring fiber brush technology ensures low friction,low contact resistance, no friction chips

How to choose slip ring models
There is no natural difference among SNK series pancake slip rings, through hole slip ring and capsule slip ring. They all can be used to conduct electricity, through hydraulic and vacuum or transmit various signals for the devices where need 360° rotating. The length of through hole slip ring and capsule slip ring can be lengthened longitudinally without limitation.But pancake slip ring transmits more current and signal channels through infinite transverse expansion on slip ring diameter (ring number). The available installation room of equipment shall be sure when you are choosing the model. If the room of rotating parts is limited, SNK series pancake slip ring can be considered. With years of researching and developing and manufacturing experience, Senring currently has a mature technology. The thickess of slip ring here even can reach to 6mm, which can meet most of the precision equipments that have compact room. Listed in the website are standard products of Senring. If you can not find suitable models here, please contact the sales personnel of Senring to make customization. All the parameters including hole size, height (thickess), OD, materials, IP grade, etc. of slip rings can be customized.
height(thickness): 6-30mm (Kinds of thickess can be customized);
hole size : Without hole(solid)~120mm,other hole size can be customized;
Rings: 2~36(more Rings can be customized; the more rings, the more current channels or signals);
More specfication: Can customize more parameters; can design through hole slip ring with any specs. according to the requirements of customers.
