REMINDERS FOR USING THESE PRODUCTS
Before using these products, be sure to request the delivery specifications.
SAFETY REMINDERS
Please pay sufficient attention to the warnings for safe designing when using these products.
When ｍounting on ｌive electrical partｓ directly, there is a fear that an insulation accident is caused, so please consider on the
design in case of use.
There is a fear that sullenness of double sided adhesive tape occurs, so please refrain from the use to a part where you wind
repeatedly by which it's for the hinge part.

MAGNETIC SHEET
Noise suppression sheets
Flexield
FEATURES
In addition to the magnetic loss effect by a magnetic layer, the noise control effect by a conduction layer is demonstrated.
As the sheet surface, it is lineup about two kinds, conductivity and insulation.
Has flexibility , it does not crack by impact or the like .
It excels in shape processability and can respond to various dimensions and shapes.
Offer by a roll shape is possible.
APPLICATION
Electromagnetic noise measures of various kinds of electronic equipment
Receiver sensitivity improvement of PEN input (inductive coupling type)
Performance improvement of RFID (on metal correspondence)
