We are pleased to announce that Seiwa Electric Co., Ltd. will be launching the "Explosion-Proof Motion Sensor." This product is an explosion-proof motion sensor that detects the approach of people and objects using microwave sensors, enabling automatic control in conjunction with various devices. It can be used in hazardous locations such as dangerous goods warehouses and plants where general human presence sensors cannot be employed, and it utilizes microwave sensors that are less prone to malfunction due to temperature changes. By linking it with warning lights and buzzers, it can alert individuals when they accidentally enter restricted areas, contributing to safety measures. Additionally, when linked with lighting fixtures, it can prevent forgetting to turn off lights in areas with low human traffic at night, thereby contributing to energy savings.

Carbon nanotubes (hereinafter referred to as CNT) are advanced materials discovered in Japan, characterized by their lightweight, high strength, and excellent elasticity and conductivity, which are being utilized in industrial products. However, CNTs have a tendency to aggregate, making it difficult to uniformly disperse them in resins or liquids. Achieving a stable and uniform dispersion is a challenge to fully realize their original performance. Our company has been developing CNT dispersants based on research results from universities and companies, utilizing our unique polysaccharide extraction technology. We are pleased to announce that we have completed the technological development for commercialization and will begin manufacturing and sales.
