Takenaka Electronic, as a manufacturer specialized in photoelectric equipment, has been devoting itself, over 40 years, to the development and production of more than 2000 products on the basis of its great experience and achievements. The photoelectric sensor is a helpful substitute for human vision in improving automatic control not only in Factory Automation but also in Home Automation, and has met with favorable acceptance in various fields, utilizing new technology and new materials. Especially, "Optical Fiber Sensor", which contains sensing and studying functions together, and "Sensor Net Work System", which enables sensor series block control and less wiring, are good examples of our high technology as a specialized manufacturer. Apart from photoelectric sensors, we have also developed a photo IC for photoelectric sensors, which is the first in this industry. We are now involved in the New Device Development field. The company continually produces "intrinsically safe" types of explosion-protection barrier relay system and industrial safety devices for presses that conform to strict national standards. Thus, we contribute greatly to various industries by providing a wide range of products.
