About Us

Founded in 1978, National Magnetic Sensors, Incorporated, is dedicated to the design, manufacture, and marketing of high quality sensors. National implemented modular sensor designs to reduce excessive lead times. We then addressed the ability to fill emergency orders. National provides countless variations of existing sensors to better suit our customers diverse problems. Our approach was then, and is now, to be easy to do business with. National was computerized in 1980, long before many manufacturers were. Early use of Fax machines facilitated sending drawings and other graphic information!
As we approach the year 2000, National continues to employ many traditional
business practices. We provide personal contact with an educated staff from the moment you call us.
