■About us

Our company designs, manufactures, and sells reed switches and reed relays.

SANYU Kogyo manufactures reed relays, while group company Standex manufactures reed switches, with bases in Tokyo, Yamanashi, Kumamoto, Sagamihara, and Osaka.

■What is a reed relay?

We customize electromechanical switching devices that contain two ferromagnetic blades inside a sealed glass tube and manufacture them for a variety of applications. They are mainly used in semiconductor automatic inspection equipment, and have grown to boast the world's top market share.

SANYU Kogyo's defect rate is also very low.
The defect rate required for reed relays is usually 50ppm.
When calculated, this means that even one defect in 20,000 units is not allowed. On the other hand, our defect rate is 10ppm.
In other words, the defect rate is one in 100,000 units.
This is an industry where products are manufactured and sold to extremely high standards.
