Silicon Steel Sensor Core


  • Application materials: Can stably provide world-class high-quality oriented silicon steel sheet materials (Baosteel, Wuhan Iron and Steel, Shougang, Nippon Steel NSC, Kawasaki JFE, POSCO, Amko AK), with optional material thicknesses of 0.05, 0.08, 0.10mm ultra-thin silicon steel sheet, 0.1mm super silicon steel, 0.23, 0.27, 0.30, 0.35mm ordinary or high magnetic induction Hi-B silicon steel sheet.
  • Structural features: Made by a self-developed high-precision automatic winding machine, it is formed through high vacuum heat treatment and shaping. An air gap is opened on the closed magnetic circuit, and is cut by wire cutting or grinding wheel. The air gap size ranges from 0.2mm-12mm, and the appearance is mainly rectangular or circular. The appearance is beautiful, the size is accurate, the performance is stable, and the residual magnetism is small. Small measurement error and high accuracy.
  • Application fields: inductors, electric quantity sensors, current sensors, Hall sensors, Hall linear integrated sensors, magnetic diodes, magnetic transistors.
  • Specification range: Customizable according to customer requirements to meet various customer specifications.
