Description: Product attributes: anti-interference degaussing ring, snap-on degaussing ring Product material: nickel zinc ferrite Product specifications: inner diameter: 3.5mm/5mm/7mm/9mm Specifications: (1) 3.5mm / 0.14in (inner diameter): suitable for 0.06-0.14in / 1.5-3.5mm cables Application: Car DVR, headset cable, speaker cable, mouse cable, keyboard cable, USB cable, etc. (2) 5mm / 0.2in (inner diameter): suitable for 0.14-0.2in / 3.5-5mm cables Application: car DVR, speaker cable, mouse cable, keyboard cable, USB cable, RS232 serial port camera cable, etc. (3) 7mm / 0.27in (inner diameter): suitable for 0.2-0.27in / 5-7mm cables Application: AV cable, coaxial audio, audio power cord, IP serial camera, etc. (4) 9mm / 0.35in (inner diameter): suitable for 0.27-0.35in / 7-9mm cables Application: cable, VGA cable, DVI cable, power cord, speaker cable, industrial cable, etc. Product color: black Whether it contains magnetic: No Product Usage: (1) Clamp on the signal line to play the role of anti-interference and electromagnetic compatibility (2) Clamp on the power cord to stabilize current and improve sound quality Scope of application: applied to all kinds of electronic connecting wires, wiring harnesses, home appliances, air conditioners, computers, inverters, electric welding machines, power cords, etc. (Note: When the wire is too thin, you can wind a few more turns at the magnetic ring to achieve Loosening effect.) Features: (1) Nickel zinc ferrite. It can improve the electromagnetic field around the solenoid to avoid external interference (2) Easy to install, easy to use, can be disassembled, there are elastic clamps on the port (3) Good performance, high efficiency and long life. Placing it near an electromagnetic source can more effectively improve the signal quality of audio and video. (4) The cable clamp will not cause the distortion of the transmission signal, nor will it affect your audio, video and picture quality product composition: 3.5MM anti-interference degaussing ring*4pcs 5MM anti-interference degaussing ring*5pcs 7MM anti-interference degaussing ring*8pcs 9MM anti-interference degaussing ring*5pcs The package includes: 22PCS degaussing rin Note: 1.
