Frequently, customers of specialty products desire “non-environmental” products as a way to keep the high quality Empire Magnetics Inc. represents. New customers may wish to test standard products to insure they have selected the correct items for their application. Empire Magnetics offers the Industrial grade (IN- versions) which provide the same performance characteristics as the environmentally conditioned products, but we use commercially accepted materials and mechanical configurations to keep the cost low. If you are just starting a project, the IN- versions may provide the least cost and the shortest time to testing a prototype.
