Electromagnetic Shielding Sheet ＜For simple EMI testing and electromagnetic interference countermeasures＞
EMC Sheet
This is a multi-functional electromagnetic wave shielding sheet developed by Medical Aid Co., Ltd.
made in Japan
Performance does not deteriorate even if folded repeatedly!
If you use a maintenance spray, it can be used for more than 5 years!
In recent years, with the development of wireless communication technology, there are many electromagnetic waves in the air. Even if you try to measure EMI during the development stage of equipment, it is not simple in places with poor electromagnetic environments. It is often the case that the measurement results are actually external noise.
EMC sheets reduce the effects of external noise and enable simple EMI measurements. EMC sheets are also effective in reducing electromagnetic interference between devices.
※If the shielding performance is too high, the effects of reflection and resonance may become greater, which may increase electromagnetic interference to the test object and other devices. EMCsheet provides an optimal environment for EMC measures.
【Features】
- ■Lightweight, compact, portable, and resistant to friction and folding
※The shielding performance does not deteriorate even after repeated folding.（When ordinary shielding mesh or sheet materials are folded, the metal parts peel off or break, causing a deterioration in performance.） - ■Conductive rust-proofing ensures performance for over 2 years, and over 5 years if maintenance spray is used
※Silver fibers that have not been treated with conductive anti-rust coating will lose their performance within about a year due to sulfidation and chlorination. - ■Good visibility and operation from outside, good heat dissipation and no need for air conditioning
- ■Just stacking them changes the shielding performance
- ■Uses silver fibers, so it is less likely to cause metal allergies like nickel-plated fabric.

Adopted as a countermeasure against pulse bombs
The high altitude electromagnetic pulse (HEMP) generated by a pulse bomb generates an electric field strength of approximately 50 kV/m (DC several 10 MHz), inducing high voltage currents in electronic devices, including information and communication devices on the ground, and in power and communication lines. It is expected that even a momentary exposure to an electric field strength of 10 kV/m or more will destroy electronic devices and electronic systems. The electromagnetic wave shielding sheet is a single-layer type that has the ability to attenuate the electric field strength to 1/50 or less, making it an effective product for countering pulse bombs for electronic devices.
Countries, local governments, and power and communication companies, which are important infrastructure facilities, need measures to protect the satellite phone terminals of the satellite phone communication network, which are the only ones that will survive a pulse bomb, from destruction. Our "electromagnetic wave shielding sheet" has been adopted by the Ministry of Defense and other organizations as an electromagnetic shielding cover to protect various electronic devices from HEMP. The reasons for its adoption are: ● Easy to attach and remove; ● Can be seen and operated from the outside; ● Does not trap heat; ● Highly resistant to folding and abrasion; ● Maintains performance for more than 10 years when stored unopened; ● No need to worry about metal allergies even when touched with your hands; and our unique high functionality and safety have been highly evaluated.
This is a honeycomb mesh electromagnetic shielding sheet. It can be used simply by covering the source of electromagnetic noise or devices that are affected by electromagnetic noise. When folded for use, the shielding performance improves depending on the number of sheets stacked.

Metal allergy is a condition in which the skin reacts to metals and chloride ions contained in sweat, causing a rash. Silver is a safe metal that is extremely unlikely to cause allergic reactions. Most common electromagnetic shielding materials use inexpensive metal plating such as nickel. Nickel dissolves more easily than other metals when it comes into direct contact with the skin, and if you sweat, it dissolves even more easily due to the action of chloride ions in sweat, so care must be taken.
Our "MGnet" products are designed to minimize the risk of metal allergies by using silver for the coating, taking into consideration the intended use and safety. Also, unlike general products that have electromagnetic shielding material coated on the fabric, "MGnet" products are silver coated at the fiber level, so they are durable and resistant to abrasion and peeling of the coating material.

How to use
Make sure the spray nozzle is facing in a well-ventilated area, hold the can 20-30cm away, shake the can 10 times, and spray thinly and evenly over the entire surface. You can use the same method up to 4-ply, but it is more efficient to spray multiple times. After spraying, let it dry indoors for about 1-2 hours.
Spray time: 1 can can spray for 270-300 seconds
The spray time varies depending on the area as follows:
20cm×20cm（400c㎡）Spray time 1 to 1.5 seconds
30cm×30cm（900c㎡）Spray Time2～3seconds
40cm×40cm（1600c㎡）Spray Time4～5seconds
50cm×50cm（2500c㎡）Spray Time6～7seconds
Frequency of use
For shielding bags and sheets that are touched daily, spray once every three months. For tents and shielding boxes that are not touched, spray after the first year and then use once within the next two years; the product's performance will hardly deteriorate even after five years or more.
※Spray frequency varies depending on usage.
