DT4C Electromegnet Iron Core
Products Description
The DT4C Electromegnet Iron Core is produced from a DT4C electrical pure iron substrate as a standardized magnetic structural component. It is assembled with plastic frames in various electromagnetic relays, where its primary function is to establish closed magnetic circuits, concentrate flux, and minimize the operating magnetoresistance of relay coils. Manufactured via an integrated cold-forging process, this product meets industry-standard iron core specifications and is well-suited for the magnetic circuit design requirements of power electronic equipment, including new energy high-voltage DC relays, industrial control signal relays, and automotive power relays. It delivers stable magnetically conductive metal component solutions for R&D and hardware procurement engineers, with full-process support grounded in material magnetic principles and controllable manufacturing processes to ensure long-term service reliability.
Key Product Features and Functions
Magnetic Circuit Conductivity
The DT4C Soft Magnetic Iron Core occupies the interior volume of the relay coil, where it serves to concentrate and distribute magnetic flux lines. This flux guidance effect substantially lowers the coil's operating magnetoresistance, enabling greater electromagnetic force to be generated at a given current level and consequently reducing the power consumption of the relay coil.
Mechanical Assembly and Positioning
The one-piece molded flange step structure directly snaps into and fixes the relay to the plastic frame, eliminating the need for additional snap-fit accessories and simplifying the overall assembly process.
Stable Operating Condition Adaptability
The Soft Magnetic Iron Relay Core's substrate impurity content is strictly controlled, preventing impurities from generating additional eddy currents and heating under alternating magnetic fields, making it suitable for continuous power supply scenarios such as new energy vehicles and energy storage converters.
Standardized Compatibility
The universal rod flange structure allows direct adaptation of the Pure Iron Core to most relay plastic frames on the market, without requiring modifications to the mold structure.
Manufacturing Advantages
One-piece molding without splicing
The Cold Forging Relay Core process eliminates the magnetic blocking layer caused by separate welded iron cores, ensuring stable magnetic conduction efficiency.
Automated production line
Fully CNC cold forging, automatic annealing, and automated inspection result in extremely low dimensional and magnetic property dispersion in batch products, enhancing manufacturing consistency.
Controllable stress process
A dedicated vacuum annealing process solves the problem of magnetic property attenuation caused by cold working, ensuring long-term magnetic stability of Soft Magnetic Iron Cores for Relays.
Flexible production line switching
The same production line can quickly switch between different rod diameters and flange thicknesses for Pure Iron Core specifications, allowing for simultaneous production of small-batch samples and large-batch orders.
Material Advantages
What sets Relay Pin Core apart is its outstanding soft magnetic performance, which is directly attributed to its ultra-low carbon level. In conventional irons, carbon precipitates as carbide particles that lock domain walls in place, increasing the coercive force required for magnetization reversal. By limiting carbon to less than 0.004%, DT4C effectively removes these pinning sites, enabling nearly free domain wall displacement and delivering both minimal coercivity and elevated permeability. This material behavior represents the key differentiating factor between DT4C and ordinary industrial pure iron or silicon steel grades.
Owing to its high-purity metallic matrix, the material delivers long-term magnetic consistency, with permeability remaining essentially unchanged throughout its service life. The Pure Iron Rod for Relay demonstrates exceptional parameter retention when subjected to harsh operating environments, such as continuous vibration, thermal cycling, and moist atmospheres. Such stability ensures compliance with the stringent reliability requirements typical of automotive and industrial automation applications.
