Circular antiinterference magnetic ring — designed to reduce electromagnetic interference, stabilize signals, and help equipment pass EMC tests without compromising its nonmagnetic nature. Key benefits Reliable EMI suppression: Reduces electromagnetic noise and interference to help connected equipment run smoothly and without unexpected resets or signal errors. EMCcompliant performance: Engineered to assist in meeting EMC requirements while maintaining its nonmagnetic nature. Durable construction: Crafted with durable materials and a sturdy design for longlasting performance in repeated use or installation environments. Multiple sizes for better fit: Available in a range of dimensions so you can select the size that matches your cable, wire bundle, or PCB passthrough. What it does for you Prevents signal degradation and intermittent faults caused by external or internal EMI sources. Lowers the risk of equipment failing EMC validation due to cable or connectorrelated emissions. Provides a compact, passive solution that integrates easily into assemblies without additional power or electronics. Important attributes Function: Electromagnetic interference shielding and antiinterference suppression. Compatibility: Multiple size options to suit different cable diameters, bundles, or board holes; select the appropriate size for effective suppression. Material and construction: Built from durable materials with a sturdy construction to ensure long service life. Performance: Designed to help pass EMC tests while preserving its stated nonmagnetic nature. Available sizes (choose the one that fits your application) 5*14.5*5.5 9.5*19.5*5.5 10*20*6.5 11.5*25*5 12*15*7.3 12*20*6.5 14.2*28.5*8 16*28*9 17.5*28.5*9.5 10*10*6 (optional) Practical use scenarios Power supplies and adapters: Slide the ring onto AC or DC leads to reduce radiated emissions and stabilize output under noisy conditions. Data and signal cables: Use on USB, HDMI, Ethernet, or other signal cables to reduce crosstalk and improve data integrity in office or industrial networks. Industrial control and consumer electronics: Install on wiring harnesses, LED drivers, or PCB throughholes to reduce interference between nearby circuits and help meet EMC requirements. Installation tips Select the size that matches the cable bundle or hole diameter for maximum effectiveness. Position the ring as close as practical to the connector, source of interference, or PCB entry point. Use one or more rings as needed: a single ring often reduces interference, while multiple rings can increase suppression for highernoise environments. If you need reliable, compact EMI suppression that helps with EMC compliance and offers longterm durability, choose the circular antiinterference magnetic ring in the size that matches your application.
