As the DT4C Iron Core component of the usually adopts a U-shaped design, which not only effectively utilizes space, but also enhances the concentration of the magnetic field, thereby improving the efficiency of the relay's pull-in. The magnetic polarity of the core is one of its important characteristics. The core has two positive and negative magnetic poles, and the armature is pulled in and released through the action of electromagnetic force.

is directly related to the performance and life of the relay. High-quality cores can increase the electrical life of the relay and reduce the voltage drop at the contact point, thereby improving the overall performance. With the development of technology, the materials and processes of the magnetic latching relay core are also constantly improving to meet a wider range of application needs.
