Noise suppression sheet
ema01002060303-01
Noise suppression sheet is used for prevention from oscillation in laptop PCs / mobile phones etc. and EMC countermeasures. By putting this sheet on problem areas, you can improve them.
 
Noise suppression sheet
for near-field high performance low frequency(300MHz-1GHz)
ema04 002070412-03
Noise suppression sheet is used for prevention from oscillation in laptop PCs / mobile phones etc. and EMC countermeasures. By putting this sheet on problem areas, you can improve them. Compared with other standard products, it has 2-3 times higher ability.
 
Super broadband wave absorption film (Transparent film)
ema03002070405-09
Configulation of a plasma display and a liquid crystal display, countermeasuring points are shown below (a picture : Configuration of display and countermeasuring points of leakage of electric wave). Usually, iron or aluminium, plastic with aluminum evaporation are used for cases. On this occasion, as countermeasures, holes of the case is blocked by conductive sheet, the case is mounted through conductive gaskets and the case is floating in the air electrically so that it won't become an antenna. But thesedays, it is a big problem that inside of a case may become a resontor and unnecessary electromagnetic wave is amplified a hundredfold and even 500 times, then some amount of wave leak from holes of a case or cables, display. To improve such problem, this super broadband wave absorption film is effective.
 
EMC shield tube (for electromagnetic protection of wire harness)
ema05139060415-02
You can easily wrap up cables with this tube by a zipper.
After setting many electric wires in a device, enwrap a harness which is banded together to increase electromagnetic shield effect.
According to a condition of using environment, you can choose combination from : 5 kinds of base materials of tube x 3 kinds of connect type x 5 kinds of additional shield.
 
RFID Improvement sheet
ema02002060304-02
When you stick RFID on a metal plate, by inserting this "RFID improvement sheet" between the plate and RFID, you can prevent deterioration of sensitivity.
 
Silicone phantom (Silicon phantom)
ema062081115-04

This is a human body phantom for driving test of a collision avoidance radar (real run test), development of radar system, specific absorption rate (SAR) measurement of mobile phone, and for a test of wearable communication. The electric constant is based on IEEE15528.
・There are such types : head only, arm only, whole body etc.. And it is possible to make a phantom to be separated its skin only.

 
Transparent wave absorber
ema07
It's transparent and it has an electromagnetic wave absorption characteristic. So this absorber is useful, for example, for ETC.
 
Electric wave absorption sheet (pyramid)
emc80
Keycom's electric wave absorption sheets (22-90GHz) are developed and manufactured with highly accurate measurement system for εr', μ'r and wave absorption amount.
