Düsseldorf, February 6, 2018 – Asahi Kasei Microdevices Corp. (AKM) agreed on January 26, 2018, to acquire the shares of Senseair AB, a Swedish manufacturer of NDIR* gas sensor modules.

Context of the acquisition
AKM is accelerating the development of business utilizing invisible optics (e.g. infrared (IR) and ultraviolet (UV)) based on its core technology for compound semiconductors. Featuring small size, high sensitivity, and high quality, AKM“s infrared (IR) light emitting elements and detectors are increasingly used in gas sensors which detect gas concentration, meeting growing needs for air quality monitoring in indoor environments such as homes, offices, and factories. Business for CO2 sensors is expected to grow rapidly in relation to measures for preventing global warming.

In 2016, AKM signed a joint development agreement with Senseair, which has a 25-year track record in the field of NDIR CO2 sensor modules. The two companies have collaboratively worked on the development of new CO2 sensors by combining Senseair“s optical path design technology and manufacturing know-how for gas sensors with AKM“s small, high-quality IR light emitting elements and detectors. One fruit of this joint development effort is a next-generation sensor featuring ultra-low power consumption that Senseair will soon launch.

Objective of the acquisition
The acquisition will make it possible for the two companies to more deeply integrate their technological knowledge and market networks. AKM expects that this will enable an expansion of business activities in the market for air, gas, and alcohol sensors, where rapid growth is forecasted.
AKM President Satoru Tamura said: „Senseair has no equal in the field of optical path design technology and manufacturing know-how. AKM has small size, low consumption infrared emitting devices and Application-Specific Integrated Circuit (ASIC) design technology, and the advantage of automotive market network and experience. We are certain that the combination of Senseair and AKM will gain a world“s leading position in the field of air, gas and alcohol sensor markets. Asahi Kasei has great respect for the world-class employees, products and technologies of Senseair Group that support the development in the fields of energy saving and driving safety“.
