EXTCOM Inc.

Design and manufacturing of compact high-precision rotary encoders, etc. from a single piece

Design, manufacturing and sales of rotary encoders and modulated wave resolvers for detecting rotational angle and position – We design and manufacture high-performance custom products from a single piece, with the concepts of compactness, high precision and high resolution. We have participated in the International Robot Exhibition and Kanagawa Robot Innovation, which are held every other year, since two years ago, and also actively participate in exhibitions held periodically by Kanagawa Prefecture and Yamato City. Regarding overseas, we launched an English website at the end of last year to promote ourselves internationally with the help of JETRO, thus entering markets in Western countries and China.

[Company strength]
We develop products with the concepts of compactness, high precision and high resolution, but also excel at customization by starting with the conceptual design after identifying the user’s needs, and design and manufacture high-performance customized products from one piece. Our president has 30 years of experience in the development and industrialization of encoders and sensors. In addition, we have good human resources and advanced technology development skills, such as joint development of encoders and sensors using the latest technology, with Sawada Laboratory of Kyushu University and Higurashi Laboratory of Tokyo University.

[Business description]
Design, manufacturing and sales of rotary encoders and modulated wave resolvers for detecting rotational angle and position – We design, manufacture and sell rotary encoders and modulated wave resolvers, which are angle and position sensors used for detecting the positions of rotating mechanisms and rectilinear mechanisms in machinery such as precision processing machines, semiconductor manufacturing devices and robots. We commercialize and sell rotary encoders and modulated wave resolvers and differentiate our products by taking advantage of original and unique new technology, and technology cultivated by our many years of experience.

[Industry]
Manufacturing of angle and position sensors

[Strength of products/technologies]
[Rotary encoder] We achieved a resolution approximately five times that of equivalent products, in a compact, high-precision and high-resolution optical rotary encoder having an outer diameter of 25 mm, a height of 24 mm and a maximum resolution of 5,000 P/R (original wave output, without multiplier circuit).
[Modulated wave resolver] An ultra-compact, ultra-thin, high-resolution, environmentally-robust resolver which is simple and compact, and detects absolute angle or position by exciting at a modulated high frequency. Our resolver outperforms conventional technology. (For an outer diameter of 25 mm, we halved the thickness and more than doubled the resolution compared with conventional products.)


[Representative's message]
We have participated in the International Robot Exhibition and Kanagawa Robot Innovation held every other year since two years ago, and also actively participate in exhibitions held periodically by Kanagawa Prefecture and Yamato City. In addition, we have participated in exhibitions since five years ago with Kyushu University and Tokyo University as a joint research company, exhibiting our rotary encoder and modulated wave resolver to expand sales channels. Regarding overseas, we launched an English website at the end of last year to promote ourselves internationally with the help of JETRO, thus entering markets in Western countries and China.

[Company structure for market development/overseas expansion]
One of our staff handles inquiries by e-mail, including technical consultation. We have set up a shared e-mail address to be read by all our staff, thus serving as a back-up. In addition, we are well-equipped to deal with overseas companies in English. We launched an English website at the end of last year to promote ourselves overseas, and were selected as an Export Promising Project Excavation Support Business by JETRO in January 2015, thus starting market research in Europe and America with the help of JETRO, with the aim of expanding overseas.




[Market share/Ranking]
We do not know our market share or rank in the industry since our products are mainly high-end customized goods, but we believe we are an industry-leader in the ultra-compact high-resolution product category.
