Industry dynamics

With its excellent performance, sensor cores have shown broad application prospects in many fields, and with the continuous advancement of technology, its future is even more worth looking forward to.

The reason why sensor cores can be widely used in many fields is inseparable from their four key characteristics: high sensitivity, good stability, excellent insulation performance and strong anti-interference ability. These characteristics are like four magic weapons, which together create the excellent performance of sensor cores.

The world of sensor cores is rich and colorful. From the perspective of materials and structures, it presents a “pluralistic world”. Different materials and structures give sensor cores different characteristics, enabling them to adapt to various complex application scenarios.

In today’s era of rapid technological development, sensor technology is like an invisible but powerful network that penetrates into every aspect of our lives. From daily smart home devices to complex industrial control systems, to power systems that ensure stable power supply, precise monitoring and control of sensors are everywhere. As the core component of sensor technology, the sensor core is like the “core engine” in this huge network, playing a vital role.

In the field of electronic component manufacturing, wire winding around Magnetic Cores is a key process, and different winding methods will have a significant impact on the performance of the magnetic core. Today, we will introduce several practical winding methods.

Permalloy, as an important soft magnetic alloy material, has many unique properties that make it significantly different from common ferromagnetic materials such as pig iron.

Permalloys can be divided into four categories according to their composition: 35%-40% Ni-Fe alloys, 45%-50% Ni-Fe alloys, 50%-65% Ni-Fe alloys and 70%-81% Ni-Fe alloys. Each type of alloy can be made into different hysteresis loop materials.

I will introduce you to an important component of power equipment - the rectangular cut air gap core, and explore its role in improving the efficiency of power equipment.

 Fe-Si alloy powder with high silicon content has high value in the commercialization and application of related devices.

Magnetization and magnetic domains are key concepts in understanding magnetic materials. Magnetization refers to the process in which the internal magnetic moments of a material tend to be arranged regularly under the action of an external magnetic field; while magnetic domains are small areas inside the material formed by spontaneous magnetization and with relatively uniform magnetic moment directions. When no external magnetic field is applied, the directions of magnetic moments of different magnetic domains cancel each other out, making the material as a whole non-magnetic to the outside.
