Capsule With Through Bore

Capsule slip ring with through bore is a new design and type in this compact capsule slip ring series of Barlin Times. Many end users require a through hole but with small size slip ring to pass small current or signal, then through hole capsule type slip rings could exactly meet this special requirement for helping some applications to save a lot of space in their equipment. At present, the standard circuits of Barlin Times capsule slip ring with through hole could be from 1-24 rings with 2A each. Adopt best gold to gold contacting materials and special technology in the inside of slip ring, also engineering plastic and metal housing are optional. The standard through bore size can be divided into 7mm, 10mm, 15mm with different diameter, Barlin Times is still continuing to design and open mould more latest miniature type of through hole capsule slip rings, which to satisfy with the demands of various industry. 

If you have specific customized requirement, please feel free to consult us so that our sales engineer could recommend the most suitable product to you for you reference.
