First Sensor AG: First Sensor concludes distribution agreement with Marubun for the sale of optical sensor solutions in Japan

Berlin and Tokyo, June 13, 2012 - On June 12, 2012, First Sensor AG (Xetra: SIS), a leading provider of individual sensor solutions, signed a distribution agreement with Marubun Corporation, one of Japan's oldest and largest distributors of semiconductor-based products, in order to place a wide range of customer-specific photodiodes on the Japanese market from the portfolio of optical sensor solutions.

First Sensor photodiodes are characterized by maximum precision, maximum speed and low dark currents, in wavelengths from ultraviolet to visible light, as well as ionizing radiation. They are used in a range of applications for various markets such as Life Science, Industrial, Mobility, Security and Aerospace. First Sensor enables the in-house development and production departments at 14 sites to offer sensor solutions from a single source and in flexible batch sizes.
Marubun covers a large proportion of Japanese demand for optical sensors on the basis of TOF (time of flight) technology, which is used for detection purposes and in measurement technology products to ensure safety, prevent danger and measure radiation. It is also used in environmental measurement.

For First Sensor, the cooperation with Marubun signifies its entry into the Japanese market. Marubun, founded in 1844, is known in Japan and beyond for its first-class relations with customers, the leading Japanese OEMs and their Asian suppliers. The company sets itself apart through its rigorous demands, professionalism and customer orientation - values that are also of great significance to First Sensor. 'Relationships with customers and, above all, trust between business partners are very important in Japan. Marubun maintains very intensive relationships with its clients. This suits our ethos and we are proud to have found the right partner to market our sensor solutions on this key sales market. We hope to see appreciably stronger revenue in Japan following a market entry phase,' confirmed Dr. Hans-Georg Giering, Chief Executive Officer of First Sensor AG.
