Electromagnetic Sheet Fanners
Electromagnetic Sheet Fanners eliminate die-damaging, double-blanking problems in automated sheet handling operations. A powerful electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up.
The on/off capability of the Electromagnetic Sheet Fanners provide operator safety during steel blank stacking and un-banding. This on/off control makes cleaning around magnets easier when sheets are not fanned. For automated presses, the electromagnetic fanners are controlled to operate simultaneously with other destacking equipment.
Electromagnetic Sheet Fanners
Electromagnetic Sheet Fanners require conversion from AC to DC voltage. IMI power supplies are designed to properly convert voltage and provide for operation of single or multiple fanners. IMI power supplies (see Tech Sheet AG-09A) can be equipped with a variable output to adjust the magnetic strength to handle a variety of metal thicknesses.
Magnet Terminology
The terminology of magnetics is not widely understood. You can find definitions of most terms on our Glossary of Magnet Terminology Page.
Rare Earth
Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world. They are also referred to as NdFeB magnets, or NIB, because they are composed mainly of Neodymium (Nd), Iron (Fe) and Boron (B). They are a relatively new invention and have only recently become affordable for everyday use.
Grades of Neodymium
N35, N38, N42, N38SH…what does it all mean? Neodymium magnets are all graded by the material they are made of. As a very general rule, the higher the grade (the number following the ‘N’), the stronger the magnet. The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) – M – H – SH – UH – EH. You find the temperature rating of each grade on our Specifications of Neodymium Magnets Page.

Platings/Coatings
Neodymium magnets are a composition of mostly Neodymium, Iron and Boron. If left exposed to the elements, the iron in the magnet will rust. To protect the magnet from corrosion and to strengthen the brittle magnet material, it is usually preferable for the magnet to be coated. There are a variety of options for coatings, but nickel is the most common and usually preferred. Our nickel plated magnets are actually triple plated with layers of nickel, copper, and nickel again. This triple coating makes our magnets much more durable than the more common single nickel plated magnets. Some other options for coating are zinc, tin, copper, epoxy, silver and gold. Our gold plated magnets are actually quadruple plated with nickel, copper, nickel and a top coating of gold.
