B&PLUS The history of the development of products

B&PLUS started from import and sales 30 years ago.  Succeeds in development of the "remote sensor" Acquisied patent after the specifications design change of the product, the production of the proximity switch. B&Plus has been  developing many original products since then.
We are continuously working on functional improvement, capacity enlargement and miniaturization. Trying further development and will continuously open up to the future of the wireles power supply.
