EMSsheet (low frequency/static magnetic field countermeasures) usage example
Electromagnetic interference (EMI) from low-frequency magnetic fields can affect a variety of electronic devices and systems, including the following, causing erroneous data transmission, monitor screen flickering, malfunctions, and deterioration of sound quality.
As a noise countermeasure against low-frequency magnetic fields from power lines and power transmission equipment
High-voltage transmission lines, transformers, switchboards, and power cables emit harmonics of 150Hz, 250Hz, 350Hz, etc. in addition to 50/60Hz AC current. Switching operations generate electromagnetic noise of several kHz to several MHz, which may cause electromagnetic interference with other equipment.
Take measures against these sources of interference by attaching EMSsheets directly to or on walls, or by placing partitions with EMSsheets attached. In addition, wrapping EMSsheets in tape around cables that are susceptible to noise can help reduce electromagnetic interference.
As a countermeasure against low to high frequency noise generated by motors
Noise generated by motors in EVs, drones, elevators, robotic machine tools, etc. is similar to that generated by the power facilities mentioned above, but the noise generated varies from a few kHz to several tens of kHz depending on the motor's rotation speed, which can cause electromagnetic interference in other equipment.
EMSsheet has high performance in the frequency band in which motors fluctuate, and by placing it appropriately, electromagnetic interference with other equipment and internal systems is reduced.
As a shielding material for electromagnetic shielded rooms that can withstand low-frequency magnetic fields
"EMSsheet" is thin and lightweight, and has a wide range of electromagnetic shielding performance from static magnetic fields to millimeter waves of 28GHz and above. Conventional shielded rooms using galvanized steel sheets have difficulty shielding static magnetic fields and low-frequency magnetic fields.
This material makes it possible to create a shielded room that can withstand static and low-frequency magnetic fields. It can be attached to plywood and boards, making it easy to install.
As a material for magnetic shielding boxes that can be used to shield low-frequency electromagnetic noise from power sources and other sources and to evaluate products
It is used in a "broadband shielding box that is also compatible with low-frequency magnetic fields" and allows for quick and easy evaluation of multiple test objects (electronic circuit boards, etc.) on a desk.Since the "EMSsheet" is adhesive-processed, multiple "EMSsheets" can be easily stacked, improving the magnetic field shielding performance according to the purpose.
