Company information
Utilizing our original technology of saturable coils, we offer a fundamentally simple magnetic detection element technology that provides high precision and long-term stability even under adverse conditions. We have received strong support from a wide range of industries, including unmanned transport carts, industrial equipment, labor-saving machines, material handling, machine tools, injection molding machines, civil engineering and construction robots, food machinery, industrial machinery, nuclear facilities, and ships. We also excel in sensors for motorsports such as F1 and Moto GP, inclinometers for construction machinery, and magnetic sensors used for ultra-high precision measurements in scientific fields. Some of our products are also used in applications like multi-story parking and golf cart guidance sensors. All of our products are developed and manufactured 100% in Japan, with over 80% of our product lineup being custom-made based on individual customer requests. We offer many custom options, including waterproof, explosion-proof, heat-resistant, water-resistant, and radiation-resistant specifications. If you have any issues related to sensing or measurement, please feel free to consult us. IoT Platform: Our sales and technical staff will fully support you, from minor customizations of existing products to proposals for new detection principles. You can also rely on us for assistance with Kaizen (continuous improvement). Our standard products come with a reassuring 3-year warranty. Location: Ina, Nagano Prefecture.
