The magnetic ring of injection molded ferrite and rubber ferrite dual code track encoder, as the core component of magnetic encoders, has been widely used in the fields of motor control, smart home appliances, and industrial automation in recent years. This type of magnetic ring achieves dual track magnetic pole design on the same magnet, which can simultaneously output position and direction signals, significantly improving the detection accuracy and stability of the system. Especially in scenes that require high angular resolution, the dual code track structure has become one of the mainstream solutions.
The use of injection molded ferrite and rubber ferrite materials has their own advantages. Injection molded ferrite has high dimensional consistency and molding freedom, suitable for integrated molding of complex structures, and also has good temperature resistance and stability. Rubber ferrite, on the other hand, is known for its excellent flexibility and cutting ability, making it suitable for applications that require lightweight, miniaturization, and strict installation space requirements. Both can achieve precise magnetic signal output through multipole magnetization, meeting the design requirements of different encoder systems.
Multi pole magnetic rings for magnetic encoders

The core advantage of the dual code disk magnetic ring lies in its high integration design. By arranging the main and secondary code tracks (usually A/B phase or absolute/incremental signals) on the same magnetic ring, not only can the system volume be reduced, but also the signal deviation caused by assembly errors can be effectively reduced. At the same time, the dual channel structure also has strong anti-interference ability and high signal redundancy, which can maintain stable output in complex electromagnetic environments.
At present, our company supplies multiple specifications of dual track magnetic rings, with 62/64 poles and 126/128 poles. The magnetic poles are evenly distributed and cost-effective.
