Contributing to the future designs and past assets of automation
Message From The President
In January 2024, M-System Co., Ltd. changes its name to MG Co., Ltd. Our company
policy is unchanged despite the new name.
For about 50 years, we have been supplying interfacing component devices in the fields of
PA/FA/BA. The company’s expertise is a collection of elements that cannot be achieved
with digital circuits alone. It includes analog circuit technology, high-voltage isolation
technology, and low-consumption and low-noise power supply design.
In the FA field, various field network technologies, miniaturization, and specialization has beenrequired, and it is the synergy of analog and digital technologies that has been creating newproducts. At the same time, the semiconductor production equipment market has been experiencing
increasing demand for the production of the previous generation of equipment, which requires continuity in factory production.
In the BA field, we are contributing to carbon neutrality by creating convenient and environmentally friendly products withnext-generation network technology.
MG Co., Ltd. will continue supplying convenient and reasonably priced products for various types of automation. We are also
determined to play a role in the next generation as a cornerstone of Japanese economy to the best of our ability by developing
and supplying products that can promote Sustainable Development Goals (SDGs).
We will continue to create new values in our products while valuing the relationship of trust with our customers.

5Our Commitment Product Development System
We have been engaged in the development of products featuring the analog circuit
technology accumulated over 50 years.

INNOVATION

Combining our own kind of analog technology and the latest digital circuit technology, we continue to supply new products at reasonable price, which are convenient
to use and meet market demand.
The continuous emphasis to budgetary and human resources ensures about 100
models of newly released products every year, which lead the market and satisfy
the ever-evolving needs of industries.

Computer-integrated flexible manufacturing systems
for high-mix, low-volume production

FLEXIBILITY

We use the production master server to manage necessary information for the
make-to-order system and manufacture the products one by one in order to realize
the high-mix, low-volume production in short lead times.
Production program is automatically created and executed by every cycle of chip
mounting process according to received orders so that there is no need of stocking
half-assembled products. 2D codes containing the program information specificto an ordered product is printed on every printed circuit board at the first stage andreferred to at every later step of production and testing.
This computer managed production system eliminates human error factors to thelimit, ensuring high productivity and reliability.

RELIABILITY

EMC countermeasures combining EMI and EMS components provide the basicmeans of dealing with electromagnetic radiation. These countermeasures must be
incorporated from the product design and development stage.
While many equipment manufacturers rely upon public testing facilities to verify
the compliance of their products with Europe’s mandatory CE marking program,
we have our own RF anechoic chamber and shielded room facilities, Kyoto Techno
Center, in order to speed the development of new products.
