Products Description
What is a soft magnetic iron rod? It is a type of soft magnetic structural component made of pure iron-characterized by low coercivity and high magnetic permeability-specifically designed for electromagnetic circuits involving low- and high-frequency switching. Serving primarily as the core of the relay's internal magnetic circuit, it replaces standard steel or alloy cores to address industry challenges such as switching lag, residual magnetism, and excessive energy consumption.
Rather than serving as a structural load-bearing part, this product functions as a core magnetic circuit component. Featuring uniform internal grain structure and extremely low impurity levels, it maintains a stable magnetic response during repeated current switching cycles, making it a fundamental component for ensuring the operational precision and consistency of relays.
Design Advantages
Optimized Step Transitions
Replacing sharp right angles of DT4C AC Relay Iron core with rounded corners (R0.3–0.5 mm) reduces stress concentration and facilitates chip evacuation during cold heading or turning.
Magnetic Isolation Design
Incorporating protrusions on the Electric Vehicle Relay Core end face instead of embedding copper inserts simplifies assembly and eliminates the risk of the inserts detaching.
Clearly Defined Plating Zones
Clearly specify which surfaces of Relay Magnetic Iron Core require plating (typically full plating) and identify any areas requiring selective masking (e.g., riveting zones).
Key Features
| Magnetic Flux Concentration | Efficiently conducts and confines the magnetic flux generated by the excitation coil, delivering it with minimal loss to the armature's working air gap to maximize electromagnetic energy conversion efficiency of Electromagnetic Relay Core. |
| Millisecond-Level Rapid Release | When the coil current drops to zero, the magnetic dipoles within the DT4C AC Relay Iron core instantly revert to a disordered state, allowing the armature to reset immediately via mechanical spring force. |
| Structural Support and Positioning Datum | The Electric Vehicle Relay Core serves as both the physical support shaft for the coil bobbin and a mounting point for riveting to the relay base, withstanding continuous mechanical impact forces. |
Quality Control
Nanoscale dimensional and geometric control
100% automated inspection of critical dimensions and geometric tolerances, with real-time SPC data analysis for Relay Magnetic Iron Core.
