\u25cf Core Advantages of Closed O Shape Magnetic Ring Assembly<\/p>\n

\u2011 Full closed O\u2011loop magnetic circuit design, effectively reduce magnetic flux leakage, uniform magnetic field, stable sensing signal and consistent adsorption force.<\/p>\n

\u2011 One\u2011piece integrated forming without splicing gap, avoid magnetic displacement and failure caused by long\u2011term vibration.<\/p>\n

\u2011 High\u2011performance NdFeB magnet core, stable magnetism, anti\u2011demagnetization under normal\u2011temperature working condition.<\/p>\n

\u2011 Flat ring structure for embedded injection molding installation, will not scratch or damage plastic shell and mold.<\/p>\n

\u2011 Multiple anti\u2011corrosion surface treatments, nickel plating, gold plating and epoxy coating for various harsh working environments.<\/p>\n<\/div>\n<\/div>\n

\u25cf Comparison: Closed O\u2011Shape VS Open Split Magnetic Ring<\/p>\n

\u2011 Magnetic performance: Closed O\u2011shape owns complete magnetic loop with low leakage; open split ring has obvious magnetic flux loss and unstable magnetic field.<\/p>\n

\u2011 Application: Closed O\u2011shape fits precision sensing, wireless charging and high\u2011reliability electronics; open split ring is suitable for simple positioning and low\u2011demand assemblies.<\/p>\n

\u2011 Molding performance: Seamless closed ring friendly for injection embedding; split ring seam may scratch plastic housing during molding.<\/p>\n

\u2011 Service life: Integral closed structure without loose risk; split ring is easy to shift under long\u2011time vibration.<\/p>\n<\/div>\n<\/div>\n
