Soft Iron Core in Relay
Products Description
The Soft Iron Core in Relay is a key magnetic component in relays, contactors, and electromagnetic drive equipment, directly affecting the equipment's engagement efficiency, energy consumption, and lifespan. As the core element for electromagnetic conversion, our soft iron core uses high-purity soft magnetic materials and is specifically designed for high-frequency, high-reliability industrial and automotive applications, ensuring excellent permeability, low coercivity, and high saturation magnetic induction.
Key Selling Points
High Permeability and Low Loss
The Core Pin for Relay uses DT4C Iron Core material, featuring high initial permeability and low remanence and coercivity. This maintains low hysteresis loss in high-frequency switching scenarios, improving relay response speed.
Precision Manufacturing Tolerances
Utilizing cold heading and precision grinding processes, cylindricity tolerance is controlled within 0.01mm. Surface roughness Ra≤0.8μm ensures a perfect fit between the Relay Pin Core and the coil.
Strong Environmental Adaptability
Nickel-plated surface, rust-free after ≥48 hours of salt spray testing. Withstands a wide operating temperature range of -40℃ to 125℃, meeting the stringent requirements of automotive and industrial equipment.
Customization Compatibility
Supports OEM/ODM; length, diameter, and slot structure can be adjusted according to customer needs to match different specifications of Relay Coil Core designs.
