A "high-frequency compatible electromagnetic wave absorption sheet" and "electromagnetic wave shielding fabric" designed for the 5G era, featuring a new absorption sheet that corresponds to the millimeter wave radar band. The materials, mixing ratios, and film thickness of the electromagnetic wave absorption layer and metal reflection layer can be customized to match the frequencies emitted by electronic devices.

A lightweight new material that shields electromagnetic waves from 100KHz to 5GHz and excels in processability such as sewing and cutting. *Flame retardant mark obtained.

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

The thin sheet that absorbs high-frequency electromagnetic waves excels in radio wave absorption performance at oblique angles, is easy to process and install due to its thin sheet form, and has excellent durability.

In recent years, the number of electronic devices and radar emitters that emit high-frequency waves has increased, and correspondingly, EMC and EMS measures have become essential. The "high-frequency compatible 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 traditional 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 has excellent durability. 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 countermeasures, unwanted radiation noise absorption, communication facility sites, countermeasures against ETC misoperation due to reflection, and ghosting issues caused by nearby metal structures in radar applications.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

The "HA-T Series" is an energy-saving automatic door sensor that opens only for those who want to enter, whether on a busy street or in a narrow passageway. The automatic door opens simply by bringing your hand close, addressing hygiene concerns even in facilities used by a large number of people. Depending on the application and installation location, you can choose between "Non-vision Mount Type/HA-T401" and "Non-vision Built-in Type/HA-T520." 【Recommended for such places!】 ☑ Entrance facing a busy passageway ☑ Presence of counters or signs near the door ☑ Buildings facing narrow passageways ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors 【Features】 ● Adaptable to various door types with four detection spot settings ● Reduces unnecessary opening and closing to minimize power consumption, contributing to energy-saving effects ● Equipped with a light touch function, allowing the door to open and close simply by waving your hand, ensuring hygiene ● Can also be used as a wide detection range non-vision infrared sensor ◎ For more details, please download the materials or contact us.

Seven Corporation has begun research and development related to rust prevention, aiming to expand the functionality of the natural multifunctional aqueous solution "SEA'S 7." This research is being promoted as a collaborative study with the Industrial Technology Research Institute. In recent years, the manufacturing industry has been seeking technologies that balance environmental impact reduction and improved work safety, making rust prevention measures after cleaning a critical issue. This research includes corrosion evaluation using metal test pieces, measurement of weight changes, and durability tests in a circulating water environment, advancing the understanding of rust prevention mechanisms and performance evaluation. In the future, we aim to develop a next-generation SEA'S 7 that incorporates rust prevention functionality in addition to cleaning, disinfection, and deodorization, contributing to the efficiency of manufacturing processes and the reduction of environmental impact.

We are pleased to announce the launch of the "Vertical Aluminum Step Type F." The "Vertical Aluminum Step Type F" is a new type of aluminum ladder specifically designed for excavation sites, based on the existing "Vertical Aluminum Step." The vertical aluminum step is lightweight due to its aluminum construction, making it easy to transport and set up. Additionally, its modular design allows for flexible height combinations (with connecting parts of 0.7m, 1.0m, and 2.0m). The newly launched Type F retains the features of the previous model while providing even greater convenience. <Features of Type F> ■ The hook adjustment range of the fixed part has been expanded. It can be attached to structures ranging from 20mm to 200mm. ■ The length of the stand pipe can be adjusted. The stand pipe can be stored, making transportation and storage easier. <Release Date> January 5, 2026 <Specifications> - Standard set for Type F: 2.4m *Individual sales of the hanging fixed part and connecting parts are available. *Sales of the previous model (stand pipe fixed type) will also continue.

This time, we will explain the differences in roles between the "accounting system" and the "document management system," which are surprisingly not well known, as well as points that are often overlooked in legal compliance. ■ The difference between accounting systems and document management systems is their "scope of coverage." - Accounting System = Management of "money (numbers)" - Document Management System = Management of "evidence (documents)" ■ Documents that are often overlooked in accounting systems The accounting system primarily focuses on "accounting processes." - "Estimates" where no money movement occurs - "Delivery notes" and "purchase orders," which are intermediate points in transactions ⇒ There are cases where these are not saved or managed in the accounting system. This could be considered a deficiency under the Electronic Bookkeeping Act. ■ Supplementing the missing parts with an "independent system" While there are high-function ERP (Enterprise Resource Planning) systems that can manage everything from estimates to invoicing seamlessly, the reality is that the cost can be a significant barrier to implementation. Therefore, there is also the option of managing documents with an independent document management system like paperlogic. Paperlogic is currently offering a free trial. Please feel free to contact us.
