About UsAbout ANGEL CO., LTD.

“We will offer high-quality products at the lowest price possible and at an opportune time for customers’ satisfactory.”

This is our mission. All of our employees join me in saying it in chorus at the meeting every morning. Since its establishment in 1961, ANGEL has been providing a wide range of switches and connectors that meet our customers’ requests. We are always dedicated to offering solutions to our customers, ranging from designing and manufacturing prototypes to mass-producing custom-made products. We use inspection apparatus of various types and kinds, including most-advanced environmental testers, to provide products which our customers can rely on.

Among international concerns are global warming and depletion of fossil energy resources, against which effective and extensive measures should be taken. We believe one of the most effective solutions to these concerns is solar power generation equipment designed for transforming sunlight into electricity, so-called “solar cell,” which has recently attracted global attention.

ANGEL started manufacturing junction boxes, a very important unit for solar cells, in 1977, leading the world in the field. More than 10 years has passed since the Kyoto Protocol was adopted in 1997 to limit world greenhouse gas emissions. In the period solar cells have rapidly come into widespread use. Under these circumstances, we have focused our efforts on the development and manufacturing of junction boxes, with successful launch of many models of them. Electrical power generated by a single solar cell is very small, but the connection of many solar cells enables us to obtain much greater electrical energy. Our products help solar cells to become low-cost power-generating devices with higher conversion efficiency and better durability.

“Save the Earth.” Contribution that we could make is humble, but all of the ANGEL people will continue
to work on ways together to contribute to international efforts for this objective.
