光洋産業 List of Products and Services

● It excels in electromagnetic wave shielding (reflection, absorption, blocking, and shielding), and since it is a conductive fabric fiber, there is no generation of static electricity, allowing the entire fabric to be grounded. ● Weight reduction: Compared to shielding measures using metal, it is lighter and has better handling properties. Ventilation holes: High breathability is achieved using conductive fabric, allowing for shielding at the hole areas. ● The fabric is made from aramid fibers that are coated with copper and nickel plating, providing high conductivity, bend resistance, and flexibility. Additionally, aramid fibers are high-performance fibers that possess heat resistance and flame retardancy, and are used in applications such as firefighting suits. ● A three-layer structure of PET yarn plated with Ni (nickel) + Cu (copper) + Ni (nickel) exhibits excellent shielding properties.

In recent years, there has been an increase in electronic devices and radar emitters that emit high-frequency waves, and correspondingly, EMC and EMS measures have become essential. The "high-frequency electromagnetic wave absorption sheet" absorbs electromagnetic waves in the gigahertz range of 5 to 110 GHz. It can be customized in terms of materials, mixing ratios, and film thickness for the electromagnetic wave absorption layer and metal reflection layer to match the frequencies emitted by electronic devices. As the speed of CPUs and other components increases, the noise frequency range is shifting to high frequencies, making it difficult for conventional ferrites and filters to prevent interference with signal waveforms, complicating noise countermeasures. This product excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and is highly durable. It is suitable for countermeasures against module TX-RX crosstalk (ETC at 5.8 GHz, X band at 8-12 GHz, ship radar at 3 GHz and 9 GHz, proximity radar at 24 GHz, local 5G at 28 GHz, high-speed wireless LAN at 60 GHz, vehicle-to-vehicle radar at 76.5 GHz, and millimeter-wave noise countermeasures from 50 GHz to 110 GHz), ground plate crosstalk measures, unwanted radiation noise absorption, communication facility sites, countermeasures against ETC misoperation due to diffuse reflection, and ghosting caused by nearby metallic structures in radar applications.

- Measures against Wi-Fi signal interference and wireless radio signal interference are supported. - Can be used as a countermeasure against RFID tag interference. - UHF band IC tags are being widely adopted, especially in logistics applications, due to their convenience of being able to read a large number of IC tags over a wide area. However, because their communication range is several meters long, they often read IC tags that are not intended to be recognized. - To prevent misreads, shield curtains, shield roll screens, and shield Roman shades are optimal. - Shield roll screens are a roll screen type that can be retracted and stored when not needed, allowing for accurate reading of IC tags without obstructing the flow of objects or people.

We offer a one-stop solution for the development of electromagnetic wave shielding materials at our in-house research institute, manufacturing at our own factory, measuring materials and methods in our in-house research facility's "anechoic chamber," design, electromagnetic wave shielding construction, and electromagnetic wave measurement (upon handover).

All made to order Maximum size up to 1,200mm × 3,600mm Can be made from either glass or resin Usable for both interior and exterior applications High transparency High shielding properties

The pipe frame structure (which does not require screws or pipe joints by the driver) allows for easy assembly and disassembly, is lightweight, compact, portable, does not occupy installation space, and is space-saving for storage, making it a simple shield room that can be set up anywhere. The shield layer (shield tent fabric) is double-layered, enabling high-performance shielding, and the floor is made of galvanized steel plates, which can be replaced only if damaged, without affecting the tent's shielding performance.

We have launched a "flame-retardant electromagnetic wave shielding membrane material" that demonstrates electromagnetic wave shielding performance even in outdoor environments and can also be used as tent material. We have developed a flame-retardant shielding membrane material that has electromagnetic wave shielding performance in outdoor environments and can independently construct structures such as tents. It can be used in a wide range of fields, including logistics and defense. 【Features】 - Electromagnetic wave shielding membrane material that is "flame-retardant" and "can be used independently outdoors" - Can be processed similarly to general tent materials - Electromagnetic wave shielding performance remains unchanged even when exposed to wind and rain - Can be used for construction purposes due to its flame-retardant properties. - Intended uses: - Radio wave shielding for factories, warehouses, and logistics hubs using RFID - Shield tents for operational command in the defense sector, shield covers for electronic equipment protection - Concert tents, circus tents, and expo pavilions that use wireless radio and wireless microphones inside - Drone training grounds where interference from radio waves needs to be eliminated *For more details, please contact us or view the PDF materials available for download in the catalog.
