Product Details

Through hole slip ring---BTH120210

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A standard through hole slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. Its inner part rotates with a rotating shaft pass through the inner hole, so we call it " through hole slip ring"   It can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

 Installation Guide:

Proper use and mounting instruction:
 ◆Slip ring can not support the weight of equipment which connected with it, rotating equipment should be fastened so that its weight will not fall on the rotor.
 ◆No force to slip ring in the direction of parallel to axis.
 ◆No damage to the surface of lead wire while equipment rotating, all lead wire can not
 bear weight while being aligned.
 ◆Because of possible geometric mismatching between the customer's system and the
 slip ring, "hard mounting "of both ends of the slip ring (i.e., securing the rotor and stator such that is NO floating during operation) is not recommended and it may cause premature failure.
 ◆Without specifying, all parameter should be within the range of specification indicated, such as :
 Working Speed
 Dielectric Strength Protection Grade
 ◆It is very precise component, please do not disassemble it .
 ◆ If start working after long time storage, please rotate it 5-10 minutes non-load.
 ◆ While working, each circuit should be with protection of over-loading to avoid being burned.
