Faraday Box, Car Key Fob Protector, Signal Blocking Metal Faraday Box for Car Keys, RFID Box for Car Security, Keyless Car Key Signal Blocker Box
This Metal material faraday box has the same function as the signal blocker bag, which can effectively block signals and prevent vehicle theft. But unlike traditional signal blocking bag, we select most effective shielding material, 100% to block all signals
The outer layer of this signal blocker box is made of stylish carbon fiber. The inner layer is made of wear-resistant metal with the best shielding effect. All you need to do is place your car key in this box your car in security
Size: 9cm X 5.2cm X 5.2cm, Weight: 68g, compact size for 1-2 Car keys, light weight for daily use
RF Blocking, EMF Radiation Protection
TOI Faraday Fabric is used for making faraday bags, EMF Radiation protection bags, Clothes, Shields, RF enclosures, EMF deflection, and signalproof rooms or tents. High-shielding nickel and copper composition blocks WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, and radio signals with 90dB average attenuation from low MHz all the way up to 40GHz. EMI, RFI, and EMF radiation shielding.
EMF Emitted by Electrical Devices
EMF includes both electrical and magnetic fields emanating from electrical devices. The electromagnetic radiation is in the frequency range of 50/60 Hz (from typical power lines) through the RF range (wireless networks at 2.4 – 5.8 GHz) up to 300 GHz (microwave devices). These frequencies are all lower than visible light which is electromagnetic radiation in the frequency of 100s of THz and is much lower in energy than ionizing radiation (e.g. the type of radiation emitted by x-ray machines and radioactive materials), and the biological effects associated with exposure are much different.
FAQ
What RF signals does this fabric block?
It is 100% shielding of WiFi (2.4 & 5GHz), Bluetooth, cell signals including 5G networks, GPS, RFID, and radio signals with 80dB-100dB average attenuation. We recommend using multiple layers of the fabric for increased shielding.
