Closed Double Row Magnetic Ring

Description

Outer Diameter(DIA)54mm

Inner Diameter(DIA)46mm

Thickness(T) 2.1mm

Our closed double-row segmented magnetic ring has a gapless O-shape with dual magnetic circuits, low leakage and even magnetic field. It outperforms single-row and open C-type rings in magnetic flux and signal stability, ideal for high-power wireless charging, precision sensors and insert molding.

As professional magnetic hardware factory, we customize OD, ID, thickness, magnet grade and surface plating for global customers, supporting sample test, small trial order and mass stable supply.

● Core Advantages

‑ Double-row closed segment splicing, dual independent magnetic circuits, stronger magnetic output, lower flux loss

‑ Gapless full O-shape structure, no displacement or demagnetization under long-term vibration

‑ Smooth flat surface, no scratch to mold and plastic housing during injection molding embedding

Two silver metal washers lie on a dark surface, one lighter and one darker in color.

Monolithic closed magnetic ring with uniform magnetism for wireless charging modules

‑ Multiple anti-corrosion plating options, stable magnetism from -20℃ to 80℃, meet RoHS standard

● Comparison with Single Row & Open C-Shape Ring

‑ Double row closed ring: Dual magnetic loop, low leakage, strong magnetism, for high-power charging & precision sensing

‑ Single row closed ring: Single magnetic circuit, medium magnetism, for conventional low-power wireless charging

‑ Open C-shape ring: Incomplete magnetic path, obvious leakage, only for simple positioning
