SM-03152050 N38H Grade Neodymium Block Magnet 39.5x17x1.75mm, Zinc Coated NdFeB Rare Earth Magnet
Features
Reliable N38H Grade Magnetic Performance: N38H grade NdFeB material delivers consistent, strong magnetic force with a residual flux density (Br) of ~12.2-12.6 kG and coercive force (Hcj) ≥ 15.9 kOe, meeting industrial-grade performance standards for everyday and specialized applications.
High-Temperature Resistance: The "H" grade thermal stability allows continuous operation at temperatures up to 120°C, preventing demagnetization and ensuring consistent performance even in environments with moderate heat exposure.
Durable Zinc Coating: The full zinc plating provides excellent anti-corrosion and anti-rust protection, shielding the magnet from oxidation, moisture, and chemical damage, ensuring long-term performance in humid or industrial conditions.
Precision Machined Dimensions: Cut to precise 39.5×17×1.75mm specifications with tight tolerances, ensuring perfect fit and alignment in custom assemblies, motors, sensors, and holding applications, eliminating the need for secondary machining.
Slim, High-Efficiency Geometry: The thin, flat rectangular design offers uniform magnetic distribution across its surface, making it ideal for compact, space-limited applications like linear motors, magnetic separators, and thin-profile electronic assemblies.
Versatile Application Compatibility: Designed for use in automotive motors, consumer electronics, industrial automation, magnetic tools, and sensor systems, offering reliable performance in both static and dynamic applications.
Quality Assured Manufacturing: Produced under strict quality control standards to ensure consistent magnetic properties, coating uniformity, and dimensional accuracy, meeting RoHS and REACH compliance requirements for safe, industrial-grade use.
